fix(love): use addCollection/createTxCollectionCUD for MeetingMinutes creation

MeetingMinutes were created via createDoc/createTxCreateDoc, which stores
attachedTo/attachedToClass/collection inside the document attributes rather
than as top-level transaction properties. The collection counter trigger in
server/middleware/triggers.ts only fires when those fields are top-level,
so the Room's `meetings` counter was never incremented and the
MeetingMinutesSection.svelte guard (`meetings > 0`) always fell through to
"No meeting minutes".

- models/love: change @model parent from core.class.Doc to
  core.class.AttachedDoc so hierarchy.isDerived works correctly
- plugins/love-resources: replace client.createDoc with client.addCollection
- server-plugins/love-resources: wrap createTxCreateDoc in createTxCollectionCUD

Fixes #10526
