fix: store volumes/mutes in profiles + fix hide rule matching

- Snapshot node volumes and mutes when saving a profile; restore
  them on load via setNodeVolume/setNodeMute for each matching node
- Fix hide rules to do exact case-insensitive match on display name
  (alias/nick) instead of regex substring match on PW name, so
  "Speaker" no longer accidentally hides "Gaming Speaker"
