Implements OPPORTUNISTIC LXMF delivery receive — single-packet encrypted messages without link establishment. BeaconCrypto.h: beacon_crypto_decrypt() — reverse of encrypt. ECDH + HKDF + HMAC verify + AES-256-CBC decrypt + PKCS7 unpad. LxmfBeacon.h: MsgpackReader for unpacking received messages. lxmf_parse_received() extracts source_hash, timestamp, title, content. lxmf_verify_signature() verifies Ed25519 against cached announce key. MessageLog.h: Extended to detect DATA packets addressed to our lxmf_source_hash, decrypt, parse, and store content. Announce entries now cache sender's ed25519 public key for verification. Gui.h: Messages screen shows LXMF content (green if verified, white if unverified) with sender name and time ago.
