fix(ui): register tencent in the Add Model provider dropdown (#40924)

* fix(ui): register tencent in the Add Model provider dropdown

The Add Model provider dropdown is driven by the proxy's
/public/providers/fields endpoint, which serves
provider_create_fields.json. Tencent was frozen in the test's
ADD_MODEL_UNLISTED_PROVIDERS set, so it never appeared in the dropdown.

Add a Tencent entry (optional api_base + required api_key, matching
TENCENT_API_BASE/TENCENT_API_KEY) and unfreeze it in the backend test.
Register Tencent in the UI Providers enum, provider_map, and placeholder
map so the dropdown resolves the display name and model placeholder.

* fix(tencent): drop test docstring to satisfy comment policy

* fix(ui): bundle the Tencent Cloud logo for the provider dropdown
