Introduce Luna.Identity project with user identity service, pairing code generation, and channel linking. Channels (Telegram, CLI) now verify link status before routing messages and prompt users to pair via the web interface. WebChannel handles /link <channel-type> <code> commands to complete the pairing flow. Fix inverted expiration check in IsPairingCodeExpired that caused codes to be treated as expired immediately after creation.
