feat(notifications): opt-in daily "nytt att bokföra" email digest (#2078)

* feat(notifications): opt-in daily "nytt att bokföra" email digest

Users asked for an email when new work arrives: bank transactions that
synced overnight and documents that landed in the inbox. Adds a daily
05:45 UTC cron (after the 05:00 bank sync) that emails opted-in users a
per-company summary with counts only, no amounts (data-minimization
stance of the kvittens/skattekonto mails).

- notification_settings.email_digest_enabled, NOT NULL DEFAULT false:
  strictly opt-in via a new toggle in the notification settings panel
- notification_log type 'bookkeeping_digest' with the claim-then-send
  partial unique index pattern: one mail per user per company per day
- counts unbooked transactions and unprocessed inbox items created in
  the last 24h; empty digests are never sent
- brand-aware sender + link base via lib/email/brand-sender
- docker crontabs regenerated from vercel.json

* fix(notifications): digest review findings in one pass

Skeptic + bot findings on PR #2078, resolved together:

- Count queries now match the canonical worklist anchors: ignored
  transactions excluded; inbox items already booked directly or matched
  to a transaction (created_journal_entry_id / matched_transaction_id)
  no longer counted (skeptic: spurious digests).
- Memberships sweep and member-email lookups chunk .in() id lists at 150
  ids to stay under proxy URL limits (HTTP 414 at ~350 opted-in users).
- Recoverable claim lifecycle (CodeRabbit): claim inserts as 'pending',
  flips to 'sent' only after the provider accepted the mail; a stale
  pending claim is atomically taken over by a later run, so a worker
  death mid-send no longer swallows the day's digest. New migration
  20260831110000 admits 'pending' to the delivery_status CHECK.
- Company name sanitized against CRLF header injection before the mail
  subject (compliance swarm ASVS V1.2.5), with test.
- RoPA entry for the new processing activity in .compliance/ropa.yaml
  (compliance swarm GDPR Art. 30).
