fix: Fixed AES-CBC crypto header parsing for payloads with large metadata, preventing malformed encrypted input from causing panics and preserving compatibility with the existing encrypted payload format.
refactor: Harden crypto error handling against padding-oracle-style information disclosure: PKCS#7 unpadding is now constant-time, and decryption/encryption failures surface only a generic error.
