refactor(devices): close all MED/LOW review items

- Extract DEVICE_ALIAS_MAX_LENGTH to src/constants/devices.ts so the
  user page and admin page share one source of truth (mirroring the
  bot's ALIAS_MAX_LENGTH=64). Was duplicated as a magic 64 in both
  files (MED-5).
- Replace ✓ / ✕ / ✏️ glyphs in AdminUserDetail.tsx with inline SVGs,
  matching the icon style already used by Subscription.tsx for the
  same rename/save/cancel actions. Eliminates the platform-dependent
  emoji rendering inconsistency (MED-4).
- Add haptic feedback to the user-side renameDeviceMutation —
  notification('success') on save, notification('error') on failure.
  Brings it in line with the other Subscription.tsx mutations
  (LOW-9).
- Translate the new rename keys into zh.json and fa.json (en.json
  already covered in the previous follow-up). Cabinet now ships full
  parity across all 4 locales for the rename UI.
