feat(decks): make deck CRUD work fully offline-first

Create / Edit / Delete deck modals now write through localDeckRepository
and fire-and-forget syncActionAtom so the change is pushed when the
network is up. EditDeckModal reads its note-type list from the
local-first noteTypesAtom instead of fetching, and the "reconnect to..."
guards on the submit buttons are gone — the user can keep working while
offline.

Soft-delete intentionally does NOT cascade to notes/cards, matching the
server's existing deck.softDelete: the deck disappears from listings and
its children become unreachable that way.
