fix: accept credentials in source config upsert (#117)

* fix: unified source config + credentials

Accept optional credentials in PUT /api/sources/:sourceId so the
dashboard can send config and credentials in a single request,
eliminating the race condition between parallel config/credential
updates that left sources uninitialized until server restart.

The existing /credentials endpoint is preserved for independent
credential updates.
