fix: resolve LocalCache override, dropdown deprecation, and shadowed extension warnings

- Rename LocalCache Dao overrides to match supertype parameter names
  (getOrCreateUser: pubkey->hex, getOrCreateNote: idHex->hex,
  getOrCreateAddressableNote: key->address) so named-argument calls stay safe.
- Replace deprecated MenuAnchorType with ExposedDropdownMenuAnchorType in the
  Buzz dropdown composables.
- Remove the buzzChannelType() extension in BuzzChannelMetadata, now shadowed by
  the equivalent (stricter) member on GroupMetadataEvent, and drop its unused
  imports.
