Fix xai probe: double /v1 URL bug, use /v1/models instead of chat completion

Browse source 
Two bugs caused all xai providers to show 'error' in the monitor:

1. Double /v1 in URL: models.json baseUrl is https://api.x.ai/v1 (OpenAI-
   compatible convention), and the probe was appending /v1/chat/completions,
   producing https://api.x.ai/v1/v1/chat/completions → HTTP 4xx.
   Fix: strip trailing /vN from baseUrl before constructing the probe URL.

2. Wrong model: probe used grok-3-mini, which requires specific x.ai
   console permissions not granted to our keys. Keys have access to
   grok-4-1-fast-reasoning only.
   Fix: use GET /v1/models instead — lightweight, no model guessing,
   returns 200 (valid key) or 401 (invalid). Includes available models
   in result for visibility.

158/158 tests pass (unit tests for parseXaiHeaders unchanged).
