- ExecStartPre copies the lego certificates into the tmpfs at each start, so
that vsftpd serves TLS after a reboot and after the first issuance.
- The lego hook only try-restarts vsftpd.
- TLS settings (TLS 1.3, default.crt) move to the local.conf and
virtual-users.conf examples; tls.conf is removed.
- The shared storage is mounted through a drop-in instead of being hardcoded.
- Add pytest integration tests (FTPS against Pebble, renewal, reboot).
