* feat(invoicing): opt-in invoice email from the company's own sending domain

Companies holding the custom_sender_domain capability grant can register
their own domain (Resend sending-only profile), publish DKIM/SPF, and once
verified every invoice email (send, reminders, recurring, payment
confirmation, MCP/v1 sends) leaves as "<name> <faktura@their-domain>"
instead of the platform sender. Reply-To is unchanged.

- New table company_sending_domains (RLS: members read, owner/admin write;
  audit trigger), types, archive-export classification.
- New capability key custom_sender_domain: manually granted per company,
  deliberately outside PAID_CAPABILITIES (never trial-seeded, never written
  by the Stripe sync). Without the grant the settings section is hidden and
  nothing changes.
- Email extension: sending-domain routes (GET/POST/PATCH/DELETE, verify),
  Resend domain lifecycle without orphan adoption, domain.updated handling
  on the delivery webhook, explicit From support in the Resend adapter.
- Core resolveInvoiceSender(): verified + enabled + entitled, else the
  platform sender; never throws.
- Settings -> Invoicing: "Avsändare vid fakturautskick" section (sv/en).
- Unit tests for the resolver, domain helpers, routes, From header; pg-real
  test for RLS and constraints.

* fix(invoicing): harden sending-domain writes, sender fallback, review findings

Skeptic refutations:
- Tenant JWTs could insert/update company_sending_domains with status =
  'verified' and an arbitrary domain through PostgREST (RLS only checked
  membership), then send invoice mail as that domain. New migration
  20260822130000 adds a BEFORE trigger: tenants may only open a pending
  claim and edit sender_local_part/sender_name/enabled; domain and
  verification state are service-role only. claim/verify helpers now take
  a service-role writer for those columns; the route's RLS client still
  does the insert.
- A company domain Resend later rejects made every invoice send fail: the
  Resend adapter retries once as the platform sender when an explicit
  company From is rejected (nothing was sent, so no double send).

Review findings:
- domain.updated webhook: discriminated outcome; DB errors answer 500 so
  Svix retries, unknown domains are acknowledged.
- Display names are RFC 5322-quoted only when they carry specials.
- Sender local part is a strict dot-atom (no trailing/consecutive dots),
  in code and in the CHECK constraint; resend_domain_id index is UNIQUE.
- IME composition guard on the claim input; event bus reset in tests;
  settings section skips its request for non-admins.

Deferred (needs a product call): persisting the effective From address in
the invoice delivery log touches the hardened evidence triggers; recorded
in DECISIONS.md.

* fix(invoicing): bind sending-domain verification to the claimed domain; fix pg test

Skeptic re-check found a TOCTOU: during the claim's Resend round-trip a
tenant could delete and re-insert its pending row under the same id with a
reserved domain, and the service-role writer updated by id alone. Now:
- the claim's verification-state write filters on (id, company_id, domain,
  resend_domain_id IS NULL) and rolls back on zero rows;
- verify and the domain.updated webhook compare Resend's domain name with
  the row before writing verified;
- resolveInvoiceSender refuses reserved platform domains and non-hostnames
  at send time (reserved-domain logic moved to lib/email/domain-name.ts and
  shared with the claim validator).

pg-real: the case-insensitive uniqueness assertion now expects the
domain_shape CHECK (lowercase enforced) for an uppercase variant and the
unique index for a same-case duplicate.

6b9338f17e feat(invoices): Betald-stämpel i faktura-PDF + betalningsbekräftelse till kund (#1700)
* feat(invoices): Betald-stämpel i faktura-PDF + betalningsbekräftelse till kund

Closes #1693. A paid faktura re-renders with a BETALD banner (paid date
and amount) and "Betalt: X" followed by "Att betala: 0"; partially_paid
gets the Betalt / Att betala (remaining) rows without a banner. Credit
notes and proformas are unchanged. Labels in sv and en.

The paid copy is its own document, a betalningsbekräftelse, never the
archived original: GET /api/invoices/[id]/pdf?variant=paid refuses
anything but status paid (409 INVOICE_PAYMENT_CONFIRMATION_NOT_PAID),
names the file Betalningsbekraftelse-<nr>.pdf and never reads or
replaces the delivery archive. invoice-pdf-source gains the
'payment_confirmation' re-render reason so the UI caveats it like any
re-render. POST /api/invoices/[id]/send-payment-confirmation emails the
paid PDF with a dedicated subject/body through the existing email
service and recipient routing, without touching status, sent_at,
journal entries or invoice_deliveries (no kind column there; logged via
the route logger instead).

Detail page: the two actions sit inside the Betald card (download paid
copy, send confirmation with an up-front confirm dialog), not in the
header row. No migrations.
