refactor(system-transforms): use shared UI primitives + drop dead i18n keys

- Replace raw <input>/<select>/<textarea>/<label> in OpEditor with shared
  Input, Select, Toggle components — matches the pattern used by every
  other settings tab in the app.
- New StringListEditor helper consolidates the three list-of-strings
  forms (needles, prefixes, words) into one consistent component.
- Replace the peer-checkbox custom provider-enable toggle with the
  shared Toggle component (same look as Adaptive Volume, LKGP, etc).
- Replace the raw add-op <select> with shared Select.
- Drop nine unused 'ccBridgeTransforms*' i18n keys left over from the
  Phase 2 v1 UI — current UI uses inline strings under the
  'CLI Fingerprint Matching' card.
- Document why systemTransforms keeps its own looser RequestBody shape
  (legacy ccBridgeTransforms RequestBody is stricter; cast at boundary).
