feat(settings): rename or re-date an existing räkenskapsår from the fiscal-year list (#2287) (#2337)

* feat(settings): rename or re-date an existing räkenskapsår from the fiscal-year list (#2287)

Inställningar > Bokföring > Räkenskapsår offered Lås, Nollställ and Skapa
nytt räkenskapsår but no way to change the name or dates of a year that
already exists, although PATCH /api/bookkeeping/fiscal-periods/[id] has
supported both (name always on an open year, dates only while the year has
no posted vouchers). The only surface over that route was the first-year
date editor under Företag, so a later or backfilled year saved with the
wrong name or dates (Aisen & Adison AB, #2286) could only be repaired in
the database.

Every open year row now gets a quiet Ändra action opening one dialog
(Namn, Startdatum, Slutdatum) that posts only the changed fields to the
existing route. Dates are read-only with the route's own reason when the
year has posted vouchers (count from the entry-count endpoint); the name
is always editable. Locked and closed years get no Ändra, matching the
route's refusal and the row's chip. Route refusals are shown inline so the
user can correct and retry.

The name follows the dates while it still has the shape fiscalYearName()
produces (new isDerivedFiscalYearName, the inverse predicate next to the
one naming helper): the customer's "Räkenskapsår 2027" corrects itself to
"Räkenskapsår 2022/2023" as the dates are fixed, and a hand-written name is
never overwritten. Saving invalidates ref:fiscal-periods so every picker
updates; the reset dialog's typed confirmation reads the name live from
the reset snapshot, so a rename does not break it.

No route change. New strings in both messages/sv.json and messages/en.json.

* fix(settings): fiscal-year edit dialog is not dirty on open when the stored name has stray whitespace

"Changed" now compares the raw input with the stored name and sends the
trimmed value only once the user has edited it; before, a stored name with
leading or trailing whitespace enabled Spara on open with a trimmed name
in the payload (CodeRabbit on #2337).
