Config Decoder

Container Parsing: Reads the binary file and extracts an encrypted payload using a length‑prefixed UTF‑8 structure.
AES‑CBC Layer 1: Tries multiple IVs to decrypt the payload with a static AES‑256 key, then unpads the result.
Colon‑Split Extraction: Splits the decrypted string by colon, takes the second base64 part, and decrypts it with a static AES‑128 key.
XXTEA Decryption: Decrypts the resulting bytes using a hardcoded XXTEA master key, yielding a JSON string.
Config JSON & Salt: If an advanced lock is active, derives an Argon2 key from a derived MasterKey and salt, then decrypts the final config with ChaCha20‑Poly1305.
Inner Field Decoding: Recursively decodes configMessage (Java‑UTF‑16 XOR) and parses embedded JSON strings.
