feat: add TelecomJS provider support with configuration and catalog i…

[baendlorel]

Problem

After registering the TelecomJS (Telecom JiangSu) in the custom provider, the model picker only shows 1 model (deepseek-v4-pro) instead of all models returned by the /v1/models endpoint.

Root Cause

refresh_catalog_cache/fetch_catalog_delta is never invoked in production — it only exists in test code. At startup, only the Models.dev catalog is refreshed, which has no entries for telecomjs. The picker therefore falls back to model_completion_names_for_provider(Telecomjs), which returns only the default model.

Fix

1. provider_lake.rs — Add merge_live_offerings() that merges new offerings into the existing live snapshot by (provider, wire_model_id) identity rather than replacing it. This allows Models.dev rows and per-provider rows to coexist.

2. client.rs — Add spawn_active_provider_catalog_refresh() associated function. When the active provider is Telecomjs, it spawns a background task that calls fetch_catalog_delta() (which already inherits metadata from the bundled catalog via case-insensitive matching) and merges all 52 models into the provider lake.

3. main.rs — Call the new function at startup, after the existing models_dev_live::spawn_background_refresh().

4. config.rs — Expand the model_completion_names_for_provider(Telecomjs) fallback list from 1 to 11 models, so the picker shows useful options even before the background refresh completes.

Testing

• cargo check --workspace — pass
• cargo test -p codewhale-config — 360 tests passed
• cargo test -p codewhale-tui (provider_lake + client catalog) — 14 tests passed
• cargo build --release — success
