* fix(vat): keep the momsrapport intact after a manual nollställning (#984)
The momsrapport already excludes settlement verifikat tagged with
source_type 'vat_settlement' (#983), but settlements booked any other
way still zeroed every ruta the moment they were posted: manual
momsomföringar booked before the tagged flow existed (the report in
issue #984), SIE-imported settlements, and storno reversals of a
settlement, which inverted the sign instead and silently doubled the
rutor after an annullera.
Exclude settlement entries by SHAPE as well: an entry with at least one
line on a declaration account (ACCOUNT_RUTA) and at least one on a
settlement net account (2650/1650) is bookkeeping about the declaration,
not VAT-bearing activity, in both the web projection
(fetchVatAccountTotals) and the MCP twin (computeVatReport).
Opening-balance entries are exempt: carried-in 26xx balances are
unsettled VAT that belongs in the next declaration.
Shape-detected POSTED settlements now also gate the "Skapa verifikat"
button through existing_entries, since the proposal re-clears the full
period and booking it on top of a manual settlement would corrupt the
26xx balances. Stornos never gate, so annullera still re-enables
booking.

* fix(mcp): stable id order for the paginated VAT-report line fetch (CodeRabbit)
fetchAllRows pages with .range(); without a unique .order() rows can
shift across page boundaries once a period exceeds 1000 lines, skipping
or double-counting journal lines in the rutor. Same discipline as the
web projection (fetch-all.ts). Pre-existing, but the query was already
being touched for #984.
Also documents the shape-rule triage from the compliance-bot review in
DECISIONS.md: compound business-VAT-plus-2650 verifikat stay a known
accepted residual (a direction guard would break the storno exclusion),
and the opening-balance concern is false for app flows (SIE import and
set_opening_balances both tag source_type 'opening_balance').
