fix(sections-editor): make the "Always" matcher option searchable by its translated label

[pedrofrxncx]

Follows the same bug class fixed in #6408 (task-board filters), found while hunting for hardening follow-ups to recent merges.

Bug: In matcher-picker.tsx, the "Always" rule's CommandItem had a hardcoded English search value ("always Target all users") while its rendered label is fully translated (alwaysLabel / targetAllUsers). cmdk's fuzzy filter matches against the value prop, not the rendered children, so a pt-BR user typing what they actually see on screen ("Sempre", "Direcionar todos os usuários") gets zero results and can't find the option — exactly the failure #6408 fixed for the assignee/repo filters.

Fix: build the search value from the same two translation keys already used for the visible label, so the searchable text always matches what's rendered in the active locale.

Verify: open the matcher picker (sections-editor rule dialog) with language: pt-BR in preferences and type "Sempre" — the "Always / Target all users" option should now show up.

Checks run locally: bun run fmt, bun test apps/web/src/components/sections-editor/matcher-picker.test.ts (8 pass), bunx oxlint apps/web/src/components/sections-editor/matcher-picker.tsx (0 warnings/errors), cd apps/web && bunx tsc --noEmit (clean). Full CI validates the rest.

Summary by cubic

Makes the "Always" matcher option searchable in all locales by building its search value from the same translated strings used in the label. Previously the CommandItem.value was hardcoded to English, so cmdk search failed for non-English users; now it matches the rendered locale with no UI change.

• Verify: switch language to pt-BR, open the sections editor matcher picker, type "Sempre" and confirm the "Always / Target all users" option appears.
