Provides a simple encrypt/decrypt API backed by OpenSSL EVP_* (available via Qt6's Network dependency which already links OpenSSL).

Key derivation: PBKDF2-SHA256, 100,000 iterations. Per-machine passphrase: QCryptographicHash::hash( QSysInfo::machineUniqueId() + "OpenSWMM-BasemapStore-v1", SHA256 ).toHex()

Cipher output format (all stored Base64): [ 16-byte salt | 16-byte IV | ciphertext ]
