Add an API-key connector

SMTP, Resend, SendGrid, Mailgun, Twilio, Tavily, Polygon, …
API-key connectors are the right fit for transactional services (email senders, SMS providers, market-data APIs). The key is encrypted on disk with AES-256-GCM; the desktop never sends it over the wire except to the worker that uses it.
Steps
- Click 'Add a connector'.
Same picker, different tab.
- Pick the kind (SMTP / Resend / Twilio / …).
The form switches to the kind-specific fields — SMTP wants host + port + user + password; Resend wants a single API key.
- Test the credentials.
Each connector has a 'Test' action that fires a real call (a no-op API round-trip, not a real send). Errors surface inline.
