fix(skattekonto): look-alike beslut rows, the list-to-voucher round trip, makulerad rendering, huvudbok discoverability (#1297)

Four fixes from the exit mail Anders Orback (Center Node AB) sent hours
after churning. His five points were mostly one job: reconciling
skattekontot against banken before årsredovisningen.

Skattekonto look-alike rows. Skatteverket splits a retroactive
omprövningsbeslut across every month it re-charges and sends one
transaction per month, sharing date, text and amount; only
ranteberakningsdatum separates them, and we stored it but rendered it
nowhere. A real company posted 15 such vouchers (67 785 kr across Feb
2025-Apr 2026) unable to tell them from duplicates of the automatic
hämtning. Surface the field when it carries information: its month
differs from the Datum column, or another row in the same band is
otherwise indistinguishable.

The list-to-voucher round trip. The verifikat list collapsed to a
skeleton on every refetch and sprang back, moving rows under the
pointer; only the first load shows a skeleton now. Filter state is
React-only, so leaving the list loses it: add a hover-revealed
open-in-new-tab affordance on the voucher list and the skattekonto page,
where the link had been behind a hand-rolled opacity-0 that coarse
pointers never trigger.

Makulerad rendering. A stornoed verifikat now reads as struck out, per
data cell rather than on the row, because text-decoration propagates and
a child cannot opt out.

Vouchers-per-account discoverability. /reports/huvudbok?account=1930
already existed; the palette matcher requires every token and the entry
never contained the word "verifikat". Add ReportDescriptor.searchTerms
plus a report-library search box.

Also fixes a false "Saknar underlag" compliance chip that flashed before
attachment counts resolved, and a keyboard-access regression where
HOVER_REVEAL_CLASS carried focus-visible only, hiding controls inside a
non-focusable wrapper from keyboard users.

No migration. No write paths, storno paths or posted entries touched.

Follow-ups filed: #1300 #1301 #1302 #1303 #1304 #1305 #1306 #1307 #1308.
Open decision: #1305 (Omförd vs Makulerad).
