feat: add in-place config editing, OpenAI GPT-oss models, and Cohere Embed v4.0

- Add PUT endpoints for editing OCI, GenAI, ADB, and MCP configurations
- Add edit buttons in all config tables with inline form pre-fill
- Add OpenAI GPT-oss 120B and 20B models to GenAI catalog
- Add Cohere Embed v4.0 (Multimodal, 1536d) to embedding catalog
- Update OCI list endpoint to return user_ocid and fingerprint for editing
- Add S.editing state management with cancel support
- Bump version to 1.4
