After conflict resolution from rebase, some imports were accidentally
removed and the CORS middleware function was eliminated but still
referenced by tests. This commit:
- Adds fmt import to api/rest/keys.go (used for error messages)
- Adds gorilla/mux import to cmd/server/main.go (used for router type)
- Restores newCORSMiddleware function to api/rest/router.go for test compatibility
- Formats code with gofmt
Add comprehensive improvements across REST and gRPC APIs:
- Add structured logging for all notification operations
- Implement HTML email support with multipart/alternative MIME
- Add CC and BCC recipient support for email notifications
- Add GetNotifiers endpoint to query available notifier configurations
- Support configurable From name in SMTP configuration
- Auto-detect content type (text vs HTML) in notification bodies
- Improve error handling and validation across all endpoints
