Add image support detection to POST /api/config/test-connection.
After the connectivity test passes, the endpoint now checks whether
the model accepts image input via two strategies:
1. Catalog fast-path: look up the model in the built-in provider
catalog (supports exact, alias, cross-provider, and vendor-prefix
stripping) and read the multimodal.input metadata directly.
2. Live probe fallback: for models not in the catalog, send a minimal
1x1 PNG image with a short prompt to the provider and interpret
the response (success → true, 4xx → false, timeout → null).
The response now includes `supportsImage` (true/false/null) and
`imageCheckSource` ("catalog" or "probe") when the connectivity
test succeeds. Failure responses are unchanged.
