decrypt_master_key.py: prints the existing master xprv after an explicit
confirmation prompt, for disaster-recovery backups. Falls back to
./data/keys/master.xprv.enc (the docker-compose.yml bind-mount path) when
.env's configured MASTER_KEY_PATH doesn't exist locally.
encrypt_master_key.py: the reverse direction — takes an externally-generated
xprv (e.g. created offline/air-gapped) via a hidden getpass prompt, validates
it parses as a private extended key, and encrypts it with the same Fernet
scheme generate_master_key.py uses. Refuses to overwrite an existing key file
unless --overwrite is passed.
Neither script is reachable via any API endpoint or the admin panel, by
design — this is the one secret the entire custodial wallet derives from.
Documented in docs/setup.md (new "Recuperare o portare una xprv esistente"
section) and CLAUDE.md's Commands block.

app/main.py assembles the lifespan-managed background tasks (Electrum
listener, round scheduler, confirmation poller, RBF bumper) and mounts
all routers behind a /health check. generate_master_key.py is the
one-time ops script that creates and Fernet-encrypts the server's
master xprv before first launch.

Minimal Electrum protocol client (client.py) plus a scripthash
subscription listener (listener.py) that watches user deposit addresses
for confirmed UTXOs, with the address->scripthash conversion helper and
a manual smoke-test script against the dev bootstrap server.
