fix: Tor management system, bug fixes, federation name sync

Major changes:
- Full Tor hidden service management via systemd path unit pattern
  (tor-helper.sh + archipelago-tor-helper.path/service) — respects
  NoNewPrivileges=yes, no sudo needed from backend
- Container doctor: prefer system Tor over container, remove archy-tor
- Deploy script: fix torrc generation (read correct services.json path),
  web apps map port 80→local port, enable both tor and tor@default
- Federation: server rename pushes name to peers via background sync
- Server name: fix root-owned file, optimistic store update
- Mesh: local echo for sent messages, sendingArch loading state
- Web5: Message button → Mesh redirect, node name lookup in messages
- PeerFiles: show DID not onion in header
- Connected Nodes: flex-1 instead of fixed max-h
- Toast notifications route to Mesh
- Deploy script: fix single-quote syntax in SSH block
