* fix(settings): scope cross-field VAT validations to saves that touch them

The settings PUT validated the whole effective record on every partial
update, so companies stored as vat_registered without a vat_number were
blocked from saving anything through the endpoint, including the invoice
bank-details dialog, which has no VAT fields (reported by a user stuck on
"Momsregistreringsnummer kravs...").

Each cross-field check (VAT completeness, 40m-monthly, periodisk
sammanstallning) now runs only when the request body touches a field in
its group, so the invariant still holds whenever VAT config is edited.
Explicit null now counts as clearing a value during validation instead of
falling back to the stored one, closing a latent hole where
{ vat_number: null } passed validation but wrote null.

* fix(invoices): gate issuance on the seller VAT number (skeptic finding)

The settings scoping in the previous commit removed what was accidentally
the only enforcement of "momsregistrerad implies momsregnr on file": with
bank details saveable again, a registered company without a stored VAT
number could issue a faktura charging moms with no seller VAT number in
the footer (mandatory element, ML (2023:200) 17 kap. 24 §).

Issuance is now gated the same way the payment account is, at all four
independent issuance points (issueAndBookInvoice, dashboard send, v1 send,
v1 mark-sent), with a structured error pointing at Installningar -> Skatt.
Credit notes, proformas, and delivery notes are exempt like the payment
gate exempts them.

Also, per the Swedish review and the secondary skeptic finding:
- PS/EU-trade edits join the VAT-completeness touch group, so enabling
  periodisk sammanstallning on an incomplete registration keeps failing.
- The stale ML 11 kap. 8 citation is updated to ML 17 kap. 24.

The makeCompanySettings fixture now models a coherent registered company
(vat_number set); the missing-number tests override it explicitly.

* fix(invoices): extend the seller-VAT-number gate to the headless issuance paths

Skeptic round 2 found three more issuance points beside the four gated in
the previous commit: the recurring auto-send service (cron, no human in
the loop), and the MCP staged-operation executors send_invoice and
mark_invoice_sent. Each carried the payment-account gate but not the VAT
gate; mark_invoice_sent additionally had a narrow settings select that
would have made a naive gate silently pass, now widened.

Recurring auto-send fails soft, matching its other guards: the invoice
stays a numbered draft with the standard schedule warning. The executors
return the structured Swedish message. Peppol send was verified
self-gating (BIS preflight requires the supplier VAT number).

* test(email): refresh brand-mail snapshots for the coherent VAT fixture

The makeCompanySettings fixture now carries a VAT number, so the invoice
and reminder mail footers correctly render the VAT line; the snapshots
predate that. Also cites ML 17 kap. 22-23 (andringsfaktura content list)
in the seller-vat-number docstring per the Swedish review suggestion,
documenting why credit notes are exempt. No behavior change.
