* Fix duplicate comment on pessimistic creation
- comment creation checks for comment's ID existence in cache
- invoice.confirmedAt included in useCanEdit deps for anons live comments
* switch to some as sets are not worth it
* only check for duplicates if a pessimistic payment method has been used
* default to empty array
* add comment about side-effects
* record ownership of an item to avoid injecting it via live comments
* trigger check only if the incoming comment is ours, cleanup
* correct conditions, correct comments, light cleanup
* fix: add defensive condition to ownership recorder, better name
* refactor: unified comment injection logic with deduplication, useCommentsView hook; revert sessionStorage-based fix
* adjust live comments naming around the codebase
* listen for hmac presence for anon edits

* flat comment injection, fetch flat comments instead of the entire subtree that would've been deduplicated anyway, cleanup
* always align new comment fragment to the comments query structure
* generic useCommentsView hook
* update comment counts if live injecting into fragments without comments field
* fix: pass parentId, if a comment has a top level parent it always has the comments field
* fix: update CommentsViewAt only if we actually injected a comment into cache
