* feat(bookkeeping): per-account default VAT, oresavrundning momsfri

Add a per-account "Standard moms" setting to the chart of accounts and use
it to auto-fill the moms on a leverantorsfaktura-rad when that konto is
picked. Oresavrundning (3740) ships as "Ingen moms", so a rounding line no
longer inherits the 25 % rad-default and skews the moms.

- chart_of_accounts.default_vat_rate (0/0.06/0.12/0.25, CHECK-constrained)
- BEFORE INSERT trigger ships 3740 momsfri on every insert path; backfills
  existing 3740 rows
- kontoplan editor: dead free-text momskod replaced with a Standard moms select
- supplier-invoice rad auto-fills the rate from the konto default

* feat(supplier-invoices): configurable start number for the ankomstnummer series

Add a company_settings.next_arrival_number start floor so a company can continue its leverantorsfaktura numbering from a previous system (e.g. Fortnox) instead of restarting the ankomstnummer at 1. get_next_arrival_number now floors the series via GREATEST(MAX(arrival_number)+1, next_arrival_number), so the floor can never move the series backwards or collide with the (company_id, arrival_number) unique index.

The RPC is hardened while rewritten: SET search_path to empty, schema-qualified refs, and an auth.uid() membership check matching generate_invoice_number.

Includes the settings UI field, sv/en strings, migration, and pg-real coverage. The CompanySettings type and Zod schema field for this feature landed earlier in 1bf3b641 (swept into the per-account VAT commit).

-- Per-account default VAT rate ("Standard moms") on the chart of accounts.
--
-- Lets a company decide, once per konto, which moms-sats a booking line should
-- default to when that konto is picked. The motivating case is oresavrundning
-- (konto 3740, Ores- och kronutjamning): a rounding line must never carry moms,
-- but the leverantorsfaktura-editor defaulted every rad to 25 %, so the moms and
-- the rounding came out wrong. NULL keeps today's behaviour (no auto-fill);
-- 0 = ingen moms. Stored as a decimal fraction to match how the app carries VAT
-- rates everywhere else (0 / 0.06 / 0.12 / 0.25).
ALTER TABLE public.chart_of_accounts
ADD COLUMN IF NOT EXISTS default_vat_rate numeric;
-- Constrain to the sats the app understands; NULL stays allowed (no default).

COMMENT ON COLUMN public.chart_of_accounts.default_vat_rate IS
'Per-account default VAT rate for booking lines (0/0.06/0.12/0.25). NULL = no default. Oresavrundning (3740) ships as 0 (momsfri).';
-- Existing companies: mark oresavrundning (3740) as momsfri so it stops
-- inheriting phantom moms. Only touches rows without an explicit value.

-- path (company seed, SIE import, on-demand backfill, manual add). The chart
-- seed function does not write a VAT column and 3740 is added on demand, so a
-- BEFORE INSERT default is the one place that covers every path. Fires only
-- when the caller left the rate unset, so an explicit choice always wins.
