feat: wire drawer toolbar filters + records table responsive hiding

Closing 2 handoff gaps:

1) DRAWER TOOLBAR FILTERS (handoff Screen 3 line 279)
SchemaDrivenForm получил три new optional props:
  - searchFilter (string) — case-insensitive substring против field key + label
  - onlyFilled (boolean) — hide fields с empty data[key]
    (null/undefined/''/false/0/empty-array/empty-object)
  - onCounterChange (visible, total) — surface field counter parent'у

Filter применяется поверх bucketing — все три buckets (identity/description/
extra) фильтруются. UI рендерит filteredBuckets.X.map(...) вместо raw bucket'ов.

В sections layout (drawer use case) если section после filter empty —
sticky header не рендерится. Tabs layout backward-compat (filter применяется
но visually invisible если user в другом tab'е).

dictionaries.$name.tsx callsite:
  - State: drawerSearch, drawerOnlyFilled, drawerCount {visible, total}
  - Reset on drawer close
  - RecordDrawer.toolbar prop wired только в edit mode (create — все поля
    empty, 'только заполненные' даст 0/0)
  - SchemaDrivenForm receives все три filter props

Result: user может typing 'mass' в drawer search → видит только mass_kg /
data_mass / etc.; toggle 'только заполненные' → hide unused optional fields.

2) RECORDS TABLE RESPONSIVE COLUMN HIDING (handoff line 466)
Records table в dictionaries.$name.tsx применяет hideBelow API из MR !59:
  - businessKey: всегда visible
  - name/code: hideBelow='md' (768px)
  - extra schema columns: hideBelow='lg' (1024px)
  - scope badge: hideBelow='sm' (640px)
  - validFrom: hideBelow='lg'
  - actions: всегда visible

На mobile 375px только businessKey + actions visible — chrome остаётся
usable. Tablet 768+ adds name/scope. Desktop 1024+ adds schema columns.

Tests: 116 pass.
