feat(approval-ux): inline draft CTA + reviewer diff summary + tightened drawer

Acts on the two "build now" items from the design review of the approval
workflow UX (other five went to TODOS.md). Plus the TODOS.md file itself,
authored during the same review.

1. **Inline "Создать черновик с моими изменениями" CTA**
   (DictionaryEditorDialog + CreateSchemaDraftModal)

   Was: when a maker edited an approval-required dict, Save disabled and a
   warning told them to "close the editor and click 'Создать черновик схемы'
   on the dict page." Three friction steps and a hunt for a button.

   Now: the warning Alert carries an action button — "Создать черновик с
   моими изменениями" — that opens CreateSchemaDraftModal in-place with the
   maker's in-progress schemaJson pre-loaded. They add a reason and submit.
   No retyping, no hunt.

   Implementation:
   - CreateSchemaDraftModal accepts optional `initialProposedSchema` prop.
     Seed order: edit-mode draft → caller pre-fill → live HEAD.
   - DictionaryEditorDialog mounts the modal inline and triggers it from the
     Alert action. Closes the editor on successful create.

2. **Diff summary chips in ReviewDrawer**

   Was: two raw JSON dumps side by side. Reviewer had to eyeball-diff long
   records to find the actual edit.

   Now: a row of summary chips above the panes — "+N added, −M removed,
   ~K changed" with the field names inline. Computed shallow client-side
   (shallowDiffSummary helper) — ordinis records are flat-ish at the top
   level, no need for a backend diff endpoint. Skipped for CLOSE op (no
   proposed) and when both sides are null.

3. **Tightened drawer header + trimmed empty-state copy**

   Was: single flex-wrap line with four spans (badge + bk + maker + ts) —
   visually busy. Plus a verbose empty-state description: "Когда maker
   отправит schema draft на ревью, он появится здесь."

   Now: two-row layout (identity row on top, provenance row below) so the
   eye lands on Badge + BK first. Empty-state copy shortened to "Очередь
   пуста" / "Схемы на ревью появятся здесь."

Other five gaps (Мои tab, full state-coverage pass, DESIGN.md, a11y audit,
maker notifications) recorded in TODOS.md.
