When selectedPrivateChatPeer was migrated to a 64-hex stable Noise key
after session establishment, file transfers would silently fail because:
1. Sender used raw 64-hex key, truncated to first 8 bytes by BinaryProtocol
2. Receiver's myPeerID is SHA256-fingerprint-derived (different value)
3. Recipient check failed, causing silent packet drop
The fix normalizes peerID to short form (SHA256-derived 16-hex) in
sendFilePrivate before constructing recipientData, ensuring the wire
format matches what receivers expect.

* PeerID 28/n: `ChatViewModel.getShortIDForNoiseKey`
* PeerID 29/n: `BLEService` + remove dupe funcs from #823
* `handleFileTransfer` to use PeerID
* `sendMessage` and `sendPrivateMessage`
* PeerID 30/n: Update some leftovers
* `lowercased()` inside PeerID for normalization
* PeerID 31/n: Remove String interop to be explicit
* MockBLEService: Remove direct target delivery
This causes a delivery even if the sender and receiver are not connected

* BinaryProtocol: add optional padding control; BitchatPacket API for padded/unpadded bytes; BLEService: use unpadded encoding and remove ad-hoc unpadding on BLE writes
* BLEService: balance BLE padding — pad Noise handshake/encrypted frames; leave public/announce/leave unpadded; keep fragmentation consistent with chosen padding
* BLEService: replace Timer with DispatchSourceTimer on bleQueue; NostrTransport: cache placeholder NoiseEncryptionService to avoid reallocation
* Unify peerID validation: InputValidator handles 16-hex, 64-hex, or alnum-/_; NoiseSecurityValidator now delegates to InputValidator
* UI: use standard green for geohash toolbar badge and count (less bright in light mode)
* UI: standardize geohash sheet green to app standard (dark: system green, light: darker green) for buttons and checkmark
* Docs: align BinaryProtocol compression docs to zlib; Logs: reduce NostrTransport DELIVERED ack logs to debug to cut noise
* Tests: add InputValidator peerID coverage and BinaryProtocol padding round-trip/length tests
* Project: ensure Xcode project reflects new tests (references added)
