fix: clean-install bugs — Tor false-installed, WG port-check honesty, encrypted backup upload

Three independent bugs surfaced during pic1 clean-install testing:

1. Tor _exit_status hardcoded configured=True regardless of whether Tor was
   actually installed.  Status now flows through the same store-installed /
   container-running bridge used by every other optional service, so Tor only
   reports installed when the container is present and running.

2. check_port_open compared the port from wg0.conf against the kernel-reported
   listening port, causing false "port closed" results whenever the conf and the
   running container were momentarily out of sync.  The function is now an honest
   liveness check: any wg0 interface that is up and has a "listening port:" line
   in `wg show` is considered open.  The check-port API endpoint now also returns
   the actual kernel listening_port and a port_mismatch flag so the UI can inform
   the user when a container recreate is needed.  (The recreate machinery already
   exists via the port-change pending-restart path; this fix makes the mismatch
   visible rather than silently lying about reachability.)

3. upload_backup only handled .zip archives; encrypted .age blobs were rejected
   with a generic error.  The endpoint now calls backup_crypto.is_encrypted() to
   detect Age-encrypted blobs and stores them verbatim as <id>.tar.gz.age with
   mode 0600 so they can be uploaded and then restored with a passphrase.  The
   plaintext zip path is unchanged.

Tests added/updated: test_connectivity_manager.py (Tor status bridge),
test_wireguard_manager.py + test_wireguard_endpoints.py (port-check liveness
and mismatch flag), test_config_backup_restore_http.py (encrypted upload
round-trip).
