Subject: [PATCH] fix: encrypted payload field sizes match firmware source
 (Mesh.cpp)

Per firmware: PAYLOAD_VER_1 uses dest(1) + src(1) + MAC(2), not 6+6+4.
Confirmed from Mesh.cpp lines 129-130: uint8_t dest_hash = payload[i++]
and MeshCore.h: CIPHER_MAC_SIZE = 2.

Changed: decodeEncryptedPayload (REQ/RESPONSE/TXT_MSG), decodeAck,
decodeAnonReq (dest 1B + pubkey 32B + MAC 2B), decodePath (1+1+2).
Updated test min-length assertions.
