feat(parties): one suggestion per legal person, rename on rebuild, review list for SCB matches, model reading for memos (#2274)

* fix(parties): one suggestion per legal person, and a later run may rename an untouched one

Found while walking the queue end to end: two voucher keys naming the same
company ("TIC identity · … The Intelligence Company AB (publ)" and
"Utbetalning leverantörsfaktura …, The Intelligence Company AB (publ)")
became two suggestions and, after Lägg upp, two suppliers; and a suggestion
made before the legal-form anchoring kept its sentence-long name for good,
because apply_party_suggestions never touched a name.

- Suggestions whose display name is anchored on a legal form read out of
  the voucher text (name_anchored) are grouped: one item, both keys as
  aliases, stats summed. Such a name also attaches to an existing party
  called exactly that, legal form included, unless an org number on either
  side says otherwise. Registered company names are unique in Sweden; a
  bank memo never groups or attaches by name.
- Migration 20260904030000: apply_party_suggestions renames a suggestion
  nobody has touched (no decision, no user or registry fact) to an anchored
  name from a later run, and reports 'renamed'. Confirmed and decided
  parties keep their names.

* fix(parties): read legal_name for exact-name attach; say a row is foreign instead of offering SCB

next build: ExistingParty had no legal_name, so the exact-legal-name index
did not compile. The query now selects it.

Queue rows whose voucher text places the company abroad show
"Utländskt bolag (Nederländerna), finns inte i SCB" instead of a search
that cannot succeed; the promote dialog counts them separately from rows
that merely lack an org number; the dossier shows the country.

* fix(parties): carry country on the dossier row

* feat(parties): one review list for SCB matches, a model reading for bank memos, refresh demoted

- Review list ("Hitta org.nr (n)" in the queue toolbar): every suggestion
  SCB could hold but that lacks an org number is asked for, one row at a
  time under SCB's rate limit; rows with exactly one active match are
  shown ticked and approved in one click, the rest keep the per-row
  picker. Nothing is written before the click.
- Model reading (lib/parties/ai-name.ts, through getAiService): when the
  rules find no legal form or country in the texts, one call reads the
  counterpart out of the bank memo; kept as a 'model' fact, shown as
  "Läst ur verifikatet", used as the query, never as a hard key. On
  demand only, never when the queue builds.
- "Uppdatera förslag" moves from the page header to a ghost button in the
  toolbar: the queue builds itself now.

* fix(parties): review list passes the dialog overflow guard; plural for match counts

* fix(parties): gate the model reading on the company's AI capability

Same gate as every other model call on company data: the capability the
company holds by plan and can switch off. No call, no fact, no reading
without it.
