fix: LND and ElectrumX Tor onion address resolution

Browse Source 
- lnd.rs: check tor-hostnames readable copy, then /var/lib/tor/, then
  legacy /var/lib/archipelago/tor/ with sudo fallback for each
- electrs_status.rs: same multi-path resolution for ElectrumX onion
- Both servers: created /var/lib/archipelago/tor-hostnames/ with readable
  copies of onion addresses (avoids sudo on every API call)
