feat(drawer): sticky toolbar API per handoff Screen 3 line 279

RecordDrawer теперь принимает optional toolbar prop:
  - search (string) — field name filter
  - onlyFilled (boolean) — show only filled fields toggle
  - counterVisible/Total (number) — 'N / M полей' caption

Sticky position между header и body, h=44 per handoff style. Toolbar
rendered только если caller передал. SchemaDrivenForm callsite (записать
filter в каждое FieldRenderer) — separate follow-up, требует refactor
form internals (currently 3 buckets identity/description/extra).

Section anchor chips + wide-mode ToC rail — deferred до backend
x-section schema metadata (CEO open question #5 в handoff).
