feat: complete migration from @hey-api/openapi-ts to openapi-react-query

- Migrated all components from useApi compatibility layer to direct React Query hooks
- Added new hooks for participant operations, room meetings, and speaker operations
- Updated all imports from old api module to api-types
- Fixed TypeScript types and API endpoint signatures
- Removed deprecated useApi.ts compatibility layer
- Fixed SourceKind enum values to match OpenAPI spec
- Added @ts-ignore for Zulip endpoints not in OpenAPI spec yet
- Fixed all compilation errors and type issues
