feat(provider,web,asr): enhance model management with explicit provider metadata (#2701)

* feat(provider,web): enhance model management with provider options

* fix(asr): enhance compatibility for ElevenLabs transcription model

* fix(provider,web): align provider availability predicates and add flow gating

* fix(web,asr): preserve legacy elevenlabs transcription configs

* fix(provider,web,asr): normalize elevenlabs configs and gate default chat models

* fix: tighten provider catalog and elevenlabs compatibility

 3. **Fallback path**: if `voice.model_name` is not set, PicoClaw performs a compatibility scan through `model_list` for legacy auto-detected ASR entries.
