Improve Sync + P2P Integration (#1265)

* Big bruh moment

* whoops

* Less stackoverflowy debug

* stuff

* Fix flawed P2P mDNS instance advertisements

* do sync when connecting with peer

* Sync after pairing

* resync_part2 all the time

* Invalidate all the things

* Invalidate whole React Query on sync event

* emit_messages_flag

* emit_messages_flag

* Backend feature flags + "emitSyncEvents" feature

* Patch `confirm` type cause Tauri cringe

* clippy

* idk but plz work

* bruh

* Fix ComLink bug

* remove log
