Jakob WennbergandClaude Fable 5 98886e68d8 fix(vat): keep the RC-basis worklist visible until every voucher is fixed (#1164)
Correcting a single voucher cleared the momsdeklaration's RC_BASIS_MISSING
error and the whole per-voucher worklist with it: the check tested mere
presence of ruta 20-24 basis, the stepper re-derived its landing step and
yanked the user to Granska mid-work, and the remounted checks card never
refetched gaps once the aggregate check stopped firing. The declaration
then claimed "klart" while the remaining vouchers still under-reported
rutor 20-24 (FK004).

- Make RC_BASIS_MISSING/RC_OUTPUT_MISSING proportional: compare reported
  basis against the basis the per-rate output boxes imply (moms/sats),
  with a 0.5% + 1 kr tolerance for per-voucher ore rounding.
- Fetch the rc-basis-gaps worklist once per period, ungated from the
  aggregate check, so remaining rows survive remounts.
- Latch the automatic stepper landing once per period so a refetch after
  a korrigering cannot navigate the user off Kontrollera.
- Resolve rc-basis-gaps against the rakenskapsar (fiscal_period_id) for
  helarsmoms, matching the declaration totals; a calendar span hid gap
  vouchers in the tail of an extended first year.
