chore: satisfy upstream lint (black, mypy, prettier, ruff)

- black/prettier reformatting across new aio code
- type annotations on db.fetchone/fetchall callsites in crud.py
- explicit dict[str, list[str]] for tag_lists in nostr_sync.py
- type:ignore[attr-defined] on Account.prvkey access — the field is
  added by the aio-fork lnbits.core.models.Account; upstream lnbits
  does not yet have it, so consumers without the fork must add a
  prvkey column to accounts before the Nostr publisher can sign.
