fix(l10n): every required locale translates every source string

[rubenvdlinde]

npm run test:l10n:parity was red on development (exit 1). It now exits 0.

What was missing

• nl: 79 strings (approval route and decision field descriptions)
• de, fr, es, it: 1,477 each
• bg, hr, da, et, fi, el, hu, ga, lv, lt, mt, pl, pt, ro, sq, is, nb, ru, tr: 1,625 each
• cs, sk, sl, sv, sr, bs, mk, uk, be, ca, lb, rm: no catalogue at all (3,301 strings each)

What changed

• l10n/<locale>.json: the missing strings are added at the end of each existing catalogue, and the 12 new catalogues are created.
• l10n/<locale>.js: regenerated with npm run l10n:build.

Only l10n/ is touched: 48 files, +73,843 / -50. The -50 are the trailing-comma line of each existing file, plus the keys 2026 and 2027 in nl.json, which a JSON rewrite moves to the top.

Dutch is written by hand. The other locales are machine translated, reuse the terms already in each existing catalogue, and use a fixed glossary for the new ones. The merge script checked that every placeholder (%s, %n, %1$d, {name}) is kept in every string. No translated value contains an em-dash.

Verified locally

• npm run test:l10n:parity: exit 1 before, exit 0 after
• npm run check:l10n-js: 0
• npm run test:l10n: 0
• npm run check:schema-l10n: 0
• npx prettier --check l10n/: 0
• No PHP changed, so composer check:strict was not run.

Known limits

• The one plural string (_in %n open vote_::_in %n open votes_) has 2 forms in every locale. That matches the default nplurals=2 the build declares, but Slavic and Baltic languages, Romanian and Irish use more forms.
• Ambiguous short strings were translated without context. "No." became a number column header, and "Put" and "Store" are guesses in some locales. A native reviewer should check these.
• test:l10n:parity is still not a CI leg (see code-quality.yml). With the backlog cleared it could be one.
