Mitra §A: pre-home (S3a/S3b/AccountInactive) + design system + Bestie Home

- Port halo_tokens + halo_theme + HaloButton to mitra_app (rose palette,
  Bricolage display, Poppins body, JetBrainsMono).
- Build S3a Input WhatsApp (figma-bestie BestieS3 first half) with
  +62 chip, leading-zero/62 normalization, allow '+' in input.
- Build S3b OTP verification (6-digit, 60s resend timer, attempts hint,
  Focus(canRequestFocus:false) for maestro inputText compat) with full
  error branching (CODE_MISMATCH, OTP_EXPIRED, OTP_USED, ATTEMPTS_EXCEEDED,
  WRONG_FLOW, ACCOUNT_INACTIVE).
- Add AccountInactive terminal screen for is_active=false mitras.
- Typed MitraAuthError with Indonesian-first localized messages +
  retryAfterSeconds passthrough.
- Rebuild home_screen.dart to match figma BestieHome (greeting + status
  card + Ganti Status CTA + Pengingat + 2-tile dark grid).
- Backend: POST /internal/_test/seed-mitra (idempotent) and
  PATCH /internal/mitras/:id (display_name update).
- Control center: inline Edit Nama on mitras row + expandable inline log
  table under clicked mitra (vs old below-table panel).
- 5 maestro flows ts-mitra-A-01/03/04/05/06 covering invalid input, happy
  path, account inactive, phone-format normalization, and the back-to-S3a
  regression. All green.

Plan + memory documented in:
- requirement/phase4-mitra-prehome-plan.md
- requirement/flow_mitra.md / flow_mitra.mermaid.md §A
