pyrage 1.3.0 removed the Recipient/Identity class pattern in favour of
pyrage.passphrase.encrypt(plaintext, passphrase) and
pyrage.passphrase.decrypt(ciphertext, passphrase) top-level functions.
Update _encrypt/_decrypt in config.py accordingly.

Add _ensure_data_dirs() helper in main.py and call it from both _run_setup()
and _start_service() so all required data directories are guaranteed to exist
before any module attempts to use them.
