Each integration card now has a Test button that re-runs its
connectivity check on demand and updates the badge in place.
- Refactors checkIntegrationStatus into checkIntegration(name) so a
single integration can be tested without firing the others.
- Adds POST /api/settings/test for the on-demand check.
- Replaces the "key exists ⇒ connected" placeholder for Tavily,
Gemini, and Nextdoor with real API calls (Tavily search, Gemini
models list, Nextdoor advertiser fetch). 401/403 surface as
"Invalid API key" / "Token expired or invalid" so a stale
credential is obvious instead of pretending to be healthy.
- Fixes Postiz auth header (was Bearer, the rest of the codebase
passes the API key bare — matches lib/postiz.ts now).
