feat(record): RecordDrawer slide-over per Stage 3.5 handoff (Phase A)

Заменяет Modal-based record create/edit на right slide-over drawer per
design_handoff_ordinis_mdm/README.md Screen 3.

What's в Phase A (drawer shell + sticky chrome):

- src/components/record/RecordDrawer.tsx (NEW)
  - Two widths: 520px default / 880px wide, toggle через ‹/› button.
    Persists в localStorage 'ord-drawer-wide'.
  - Sticky header: caption (cap style) + recordId mono + width-toggle +
    history button (edit mode) + ×.
  - Sticky footer: [Удалить] (danger, edit mode) · 'не сохранено · N полей'
    caption · [Отмена] · [Сохранить] (drives form submit через form attr).
  - Built на shadcn Sheet primitive + Radix Dialog. Override sheetVariants
    inline для transition-able max-width (variant size не toggle'ится
    smoothly без animate prop).
  - aria-labelledby wires DialogTitle к содержимому header.
  - Mobile <880px: w-full fullscreen (per handoff responsive table).

- src/components/form/SchemaDrivenForm.tsx
  - New optional props: formId, onDirtyChange.
  - Когда formId передан — внутренний FormActions footer прячется (drawer
    footer driving submit через <button form={formId} type=submit>).
  - Dirty-count считается из RHF formState.dirtyFields (top-level + data.*).
  - useEffect surfaces count к parent — drawer footer caption updates live.

- src/routes/dictionaries.$name.tsx
  - Modal create/edit -> RecordDrawer.
  - State: + recordDirtyCount (reset на close).
  - onDelete wires к existing close-confirm flow (kind: 'close-confirm').
  - onHistory wires к existing setHistoryKey RecordHistoryDrawer.

- src/i18n.ts
  - + form.delete, form.unsavedNFields_one/few/many/other (i18next plural rules).
  - + drawer.{collapse,expand,close,captionEdit,captionCreate}.

Phase B (TODO Stage 3.5b — separate MR):
- Section anchor chips (sticky strip)
- Wide-mode left ToC rail (180px)
- Sticky toolbar: search + 'только заполненные' toggle + counter
- Requires x-section schema metadata в backend properties (CEO open question #5 в handoff)

Tests: 8 files, 116 tests pass. TS strict clean.
