Remove Obsidian integration for public server deployment

Obsidian relied on local filesystem access which is incompatible with
public server deployment. This removes all Obsidian-related code including:

- API client and interface
- Store layer methods (SaveNotes, GetNotes, SearchNotes)
- Handler methods and routes
- UI tab and templates
- Configuration fields
- Related tests
