fix: add DeleteCertificateDialog component with confirmation dialog for certificate deletion

- Implement DeleteCertificateDialog component to handle certificate deletion confirmation. - Add tests for DeleteCertificateDialog covering various scenarios including rendering, confirmation, and cancellation. - Update translation files for multiple languages to include new strings related to certificate deletion. - Create end-to-end tests for certificate deletion UX, including button visibility, confirmation dialog, and success/failure scenarios.

 This prevents certificate accumulation and keeps your system tidy.

+## Manual Certificate Deletion
+
+Over time, expired or unused certificates can pile up in the Certificates list. You can remove them manually:
+
+| Certificate Type | When You Can Delete It |
+|------------------|----------------------|
+| **Expired Let's Encrypt** | When it's not attached to any proxy host |
+| **Custom (uploaded)** | When it's not attached to any proxy host |
+| **Staging** | When it's not attached to any proxy host |
+| **Valid Let's Encrypt** | Managed automatically — no delete button shown |
+
+If a certificate is still attached to a proxy host, the delete button is disabled and a tooltip explains which host is using it. Remove the certificate from the proxy host first, then come back to delete it.
+
+A confirmation dialog appears before anything is removed. Charon creates a backup before deleting, so you have a safety net.

+# Manual Testing: Certificate Deletion UX Enhancement
+
+## Description
+
+Manual test plan for expanded certificate deletion. Focuses on edge cases and race conditions that automated E2E tests cannot fully cover.
+
+## Pre-requisites
+
+- A running Charon instance with certificates in various states:
+  - At least one expired Let's Encrypt certificate **not** attached to a proxy host
+  - At least one custom (uploaded) certificate **not** attached to a proxy host
+  - At least one certificate **attached** to a proxy host (in use)
+  - At least one valid (non-expired) Let's Encrypt production certificate not in use
+- Access to the Charon Certificates page
+
+## Test Cases
+
+### Happy Path
+
+- [ ] **Delete expired LE cert not in use**: Click the delete button on an expired Let's Encrypt certificate that is not attached to any proxy host. Confirm in the dialog. Certificate disappears from the list and a success toast appears.
+- [ ] **Delete custom cert not in use**: Click the delete button on an uploaded custom certificate not attached to any host. Confirm. Certificate is removed with a success toast.
+- [ ] **Delete staging cert not in use**: Click the delete button on a staging certificate not attached to any host. Confirm. Certificate is removed with a success toast.
+
+### Delete Prevention
+
+- [ ] **In-use cert shows disabled button**: Find a certificate attached to a proxy host. Verify the delete button is visible but disabled.
+- [ ] **In-use cert tooltip**: Hover over the disabled delete button. A tooltip should explain that the certificate is in use and cannot be deleted.
+- [ ] **Valid LE cert hides delete button**: Find a valid (non-expired) Let's Encrypt production certificate not attached to any host. Verify no delete button is shown — Charon manages these automatically.
+
+### Confirmation Dialog
+
+- [ ] **Cancel does not delete**: Click the delete button on a deletable certificate. In the confirmation dialog, click Cancel. The certificate should remain in the list.
+- [ ] **Escape key closes dialog**: Open the confirmation dialog. Press Escape. The dialog closes and the certificate remains.
+- [ ] **Click overlay closes dialog**: Open the confirmation dialog. Click outside the dialog (on the overlay). The dialog closes and the certificate remains.
+- [ ] **Confirm deletes**: Open the confirmation dialog. Click the Delete/Confirm button. The certificate is removed and a success toast appears.
+
+### Keyboard Navigation
+
+- [ ] **Tab through dialog**: Open the confirmation dialog. Press Tab to move focus between the Cancel and Delete buttons. Focus order should be logical (Cancel → Delete or Delete → Cancel).
+- [ ] **Enter activates focused button**: Tab to the Cancel button and press Enter — dialog closes, certificate remains. Repeat with the Delete button — certificate is removed.
+- [ ] **Focus trap**: With the dialog open, Tab should cycle within the dialog and not escape to the page behind it.
+
+### Edge Cases & Race Conditions
+
+- [ ] **Rapid double-click on delete**: Quickly double-click the delete button. Only one confirmation dialog should appear. Only one delete request should be sent.
+- [ ] **Cert becomes in-use between dialog open and confirm**: Open the delete dialog for a certificate. In another tab, attach that certificate to a proxy host. Return and confirm deletion. The server should return a 409 error and the UI should show an appropriate error message — the certificate should remain.
+- [ ] **Delete when backup may fail (low disk space)**: If testable, simulate low disk space. Attempt a deletion. The server creates a backup before deleting — verify the error is surfaced to the user if the backup fails.
+- [ ] **Network error during delete**: Open the delete dialog and disconnect from the network (or throttle to offline in DevTools). Confirm deletion. An error message should appear and the certificate should remain.
+
+### Visual & UX Consistency
+
+- [ ] **Dialog styling**: The confirmation dialog should match the application theme (dark/light mode).
+- [ ] **Toast messages**: Success and error toasts should appear in the expected position and auto-dismiss.
+- [ ] **List updates without full reload**: After a successful deletion, the certificate list should update without requiring a page refresh.

+
+## Code Review Observations
+
+### Quality Assessment
+
+1. **Delete button visibility logic** — Correct. `isDeletable()` and `isInUse()` are exported
+   pure functions with clear semantics, tested with 7 cases including edge cases (no ID,
+   `expiring` status, `certificate.id` fallback via nullish coalescing).
+
+2. **Dialog accessibility** — Correct. Uses Radix Dialog (focus trap, `role="dialog"`,
+   `aria-modal`). Disabled buttons use `aria-disabled="true"` (not HTML `disabled`) keeping
+   them focusable for Radix Tooltip. Delete buttons have `aria-label` for screen readers.
+
+3. **Removed duplicate backup** — The client-side `createBackup()` call was correctly removed
+   from the mutation. The server handler already creates a backup before deletion (defense in
+   depth preserved server-side).
+
+4. **Provider detection** — Uses `cert.provider === 'letsencrypt-staging'` instead of the
+   fragile `cert.issuer?.toLowerCase().includes('staging')` check. This aligns with the
+   canonical `provider` field on the model.
+
+5. **Warning text priority** — `getWarningKey()` checks `status === 'expired'` before
+   `provider === 'letsencrypt-staging'`, so an expired staging cert gets the "expired" warning.
+   This is tested in `DeleteCertificateDialog.test.tsx` ("priority ordering" test case).
+
+6. **i18n** — Non-English locales (`de`, `es`, `fr`, `zh`) use English placeholder strings
+   for the 10 new keys. The existing `noteText` key was also updated to English in all locales.
+   This is consistent with the project's approach of adding English placeholders for later
+   translation.
+
+7. **Comment fix** — `ssl_certificate.go` line 13: Provider comment updated from
+   `"self-signed"` to `"letsencrypt-staging", "custom"` — matches actual provider values in the
+   codebase.
+
+8. **E2E test design** — Uses real X.509 certificates (not placeholder PEM), direct API seeding
+   with cleanup in `afterAll`, and standard Playwright patterns (`waitForDialog`,
+   `waitForAPIResponse`). Tests cover: page load, delete button visibility, dialog open/cancel/
+   confirm, in-use tooltip, and valid LE cert exclusion.
+
+### No Issues Found
+
+- No XSS vectors (dialog content uses i18n keys, not raw user input)
+- No injection paths (backend validates numeric ID via `strconv.ParseUint`)
+- No authorization bypass (DELETE endpoint requires auth middleware)
+- No race conditions (server-side `IsCertificateInUse` check is defense in depth)
+- No missing error handling (mutation `onError` displays toast with error message)
