chore: merge main, resolve biome formatting conflicts

Merge origin/main into feat/external-2fa-codes. Resolve formatting
conflicts caused by biome rollout; preserve both feature streams:
PR's external 2FA token + signing-session 2FA proof additions plus
main's RateLimit/RecipientExpired/signingReminders/date-auto-insert.

In complete-document-with-token.ts, drop the duplicate early
field-fetching block introduced when main moved that logic later
with date auto-insert support; keep the EXTERNAL_TWO_FACTOR_AUTH
check using derivedRecipientActionAuth.
