Implement STIM bundle decryption and installation

- Updated `Worker.handleDeploy` to handle STIM bundles using `ExtractProfileBundle` and `ExtractMinerBundle`.
- Used `PeerConnection.SharedSecret` as the password for decryption.
- Implemented logic for `BundleProfile`, `BundleMiner`, and `BundleFull`.
- Fixed broken files `pkg/node/dispatcher.go` and `pkg/node/peer.go` to ensure compilation and testing.
- Updated tests in `pkg/node/worker_test.go` and added coverage for deployment logic.
