feat: Enhance LiveLogViewer with Security Mode and related tests

- Updated LiveLogViewer to support a new security mode, allowing for the display of security logs.
- Implemented mock functions for connecting to security logs in tests.
- Added tests for rendering, filtering, and displaying security log entries, including blocked requests and source filtering.
- Modified Security page to utilize the new security mode in LiveLogViewer.
- Updated Security page tests to reflect changes in log viewer and ensure proper rendering of security-related components.
- Introduced a new script for CrowdSec startup testing, ensuring proper configuration and parser installation.
- Added pre-flight checks in the CrowdSec integration script to verify successful startup and configuration.

+### 6. GolangCI-Lint
+
+**Status:** ✅ PASS (after fixes)
+
+**Initial Issues Found:** 9 issues
+
+**Issues Fixed:**
+
+| File | Issue | Fix Applied |
+|------|-------|-------------|
+| `internal/api/handlers/cerberus_logs_ws_test.go:101,169,248,325,399` | `bodyclose: response body must be closed` | Added `//nolint:bodyclose` comment - WebSocket Dial response body is consumed by the dial |
+| `internal/api/handlers/cerberus_logs_ws_test.go:442,445` | `deferInLoop: Possible resource leak, 'defer' is called in the 'for' loop` | Moved defer outside loop into a single cleanup function |
+| `internal/api/handlers/cerberus_logs_ws_test.go:488` | `httpNoBody: http.NoBody should be preferred to the nil request body` | Changed `nil` to `http.NoBody` |
+| `internal/caddy/config_extra_test.go:302` | `filepathJoin: "/data" contains a path separator` | Used string literal `/data/logs/access.log` instead of `filepath.Join` |
+| `internal/services/log_watcher.go:91` | `typeUnparen: could simplify type conversion` | Added explanatory nolint comment - conversion required for channel comparison |
+| `internal/services/log_watcher.go:302` | `equalFold: consider replacing with strings.EqualFold` | Replaced with `strings.EqualFold(k, key)` |
+| `internal/services/log_watcher.go:310` | `builtinShadowDecl: shadowing of predeclared identifier: min` | Renamed function from `min` to `minInt` |

+
+## Files Modified During Audit
+
+1. `backend/internal/api/handlers/cerberus_logs_ws_test.go`
+   - Added nolint directives for bodyclose on WebSocket Dial calls
+   - Fixed defer in loop resource leak
+   - Used http.NoBody for non-WebSocket request test
+
+2. `backend/internal/caddy/config_extra_test.go`
+   - Fixed filepath.Join with path separator issue
+   - Removed unused import `path/filepath`
+
+3. `backend/internal/services/log_watcher.go`
+   - Renamed `min` function to `minInt` to avoid shadowing builtin
+   - Used `strings.EqualFold` for case-insensitive comparison
+   - Added nolint comment for required type conversion
+
+---
+
+## Recommendations
+
+None - all checks pass and the codebase is in good condition.
