Ensure node numeric aliases are derived from canonical IDs

[l5yth]

Summary

• derive the node numeric alias from either the payload or the canonical Meshtastic node ID
• persist the derived alias during node upserts so message queries can join on numeric senders

Testing

• ruby -c web/app.rb
• bundle install (fails: Gem::Net::HTTPClientException 403 "Forbidden")
