fix(fonts): semantic typography utilities per handoff (7 roles)

Заменяет blanket override из MR !45 на типизированную type scale per
design_handoff_ordinis_mdm/README.md "Scale" section.

Семь semantic @utility в styles.css:
  text-title-xl  22/600   — modal title, section header
  text-title-lg  17/600   — page title в editor
  text-title-md  15/600   — dictionary card title
  text-body      13/400   — workhorse: body, buttons, tabs, inputs
  text-cell      12.5/500 — table cell text
  text-mono      11/500   — Mono: IDs, dates, FK refs (font-mono baked in)
  text-cap       10.5/600 — Tektur UPPERCASE caption (font/uppercase baked in)

Audit phases:
  P1: добавил 7 утилит, font/uppercase/tracking baked где надо
  P2: 43 deterministic codemods (font-mono+text-2xs/[11px] → text-mono,
      [15/17/22]px+font-semibold → text-title-*, [12.5]px → text-cell,
      [10.5]px+uppercase+tracking → text-cap)
  P3: 64 text-sm → text-body (handoff workhorse), 84 text-2xs context-aware
      (TableCell → text-cell, bare → text-cell, плюс cleanup caps в backticks
      template literals который Phase 2 пропустил), 25 text-xs (6 → text-mono
      когда с font-mono, 19 → text-cell), 8 titles text-base/lg → text-title-*
  P4: убрал --text-2xs override (no users), оставил --text-sm: 13px scoped
      к @nstart/ui passthrough (см. comment в styles.css — убирается в Stage 3.9)

Stats:
  text-body: 69 | text-cell: 99 | text-mono: 50 | text-cap: 42
  text-title-xl: 5 | text-title-lg: 5 | text-title-md: 7
  text-sm/text-2xs/text-xs в src/: 0 (только в styles.css комментариях)

Поведение всех 277 typography usages теперь явно соответствует handoff —
каждое место осознанно выбрано под роль, не плажирующий override.
