When editing a proxy host with certificate_id set to null (auto), the
dropdown would not show "Managed by Caddy (Auto)" as selected and it
would revert to another certificate. There were two issues:
1. Form submission: Empty string from dropdown was treated as falsy,
returning undefined instead of null (means "don't change")
2. Database update: The ?? operator treated null as falsy and fell back
to existing value instead of saving null
Changes:
- app/(dashboard)/proxy-hosts/actions.ts: Check formData.has() and
explicitly convert empty string to null for auto mode
- src/lib/models/proxy-hosts.ts: Use !== undefined instead of ?? to
allow null values to be saved
- app/(dashboard)/proxy-hosts/ProxyHostsClient.tsx: Add Certificate
column to table showing "Managed by Caddy (Auto)" for auto certs
Applied same fixes to access_list_id for consistency.
Now when users select "Managed by Caddy (Auto)", it correctly sets
certificate_id to null, displays properly on subsequent edits, and
shows in the table view.
