Pull request overview
This PR implements automatic model selection when AI provider credentials are configured, improving the onboarding experience. When users add their first AI provider configuration, the system now intelligently selects appropriate chat and edit models. Additionally, the PR fixes an issue where certain configuration fields (like Azure base URL) were not being saved properly due to incorrect placement of the disabled prop.
Changes:
- Added logic to auto-populate chat and edit models based on configured AI provider credentials
- Refactored model registry to track default models per provider
- Fixed form field handling by moving
disabledprop to actual input elements instead of FormField wrapper

## 📝 Summary <!-- Provide a concise summary of what this pull request is addressing. If this PR closes any issues, list them here by number (e.g., Closes #123). --> Fixes #7915 . There's a bug with custom provider config. When editing a field (e.g., base_url), the API key gets lost. This happens because: 1. Frontend sends only dirty fields (getDirtyValues) 2. custom_providers is in `replace_paths`, so the partial update replaces the entire object `replace_paths` was added because deep merge can't delete providers - omitting a key means "don't change" not "delete". I was iterating through some solutions Option 1: Sentinel values in deep_merge - Remove custom_providers from replace_paths - Detect ******** during merge → preserve existing secret - Use "__DELETED__" → remove the key Option 2: Frontend sends complete object - Keep replace_paths behavior - Frontend always sends full object when on replace_paths This PR is option 2, both options feel hacky. ## 🔍 Description of Changes <!-- Detail the specific changes made in this pull request.
