feat(mistral-ai): update model YAMLs [bot]

[models-bot]

Auto-generated by poc-agent for provider mistral-ai.

---

Note

Low Risk
Metadata-only YAML changes to param stripping and doc links; no runtime logic or security-sensitive behavior.

Overview
Updates voxtral-mini-tts-2603 provider metadata so it no longer inherits reasoning_effort from the Mistral provider defaults (added to removeParams alongside existing TTS-specific param stripping).

Also adds https://mistral.ai/pricing/api to sources for documentation traceability.
