feat(settings): standard verifikationsserier for new companies, opt-in action for existing (#2358)

* feat(settings): standard verifikationsserier for new companies, opt-in action for existing (#2184)

A new company_settings row now defaults to the standard series set
(A manual/bank, B kundfakturor, C inbetalningar, D leverantörsfakturor,
E utbetalningar, H periodisering, I bokslut, K lön, L kontantfaktura,
M moms) instead of everything on A. The set lives once, as the
exhaustive STANDARD_VOUCHER_SERIES_MAP in the resolver; a pg-real test
holds the column default equal to it and to the source_type CHECK.

Existing rows are not remapped: the per-type settings form gets an
"Använd standarduppsättningen" action that fills the set for review
and save through the existing PUT, so the switch is a deliberate,
audited act rather than a mid-year numbering change nobody decided.
Payment rows bound to the other bokföringsmetod are dimmed, not hidden.

* test(bookkeeping): fresh company_settings row asserts the standard series set, not all-A

voucher-series-defaults.pg.test.ts codified the pre-#2184 column default
(every source type on A). Migration 20260906210500 replaces that default
with the standard set, so the "freshly inserted row" case now asserts the
representative letters and full equality with STANDARD_VOUCHER_SERIES_MAP.
The explicit-override case keeps proving a company's own layout replaces
the default wholesale. No other pg or tool test asserted on the old map.
