fix: align frontend bulk action types with backend API contract

- Fix BulkActionType enum: 'extend' → 'extend_subscription',
  'cancel' → 'cancel_subscription', 'activate' → 'activate_subscription'
- Fix BulkActionParams: 'balance_kopeks' → 'amount_kopeks' to match backend
- Fix SSE complete handler: build errors from progress log (backend
  complete event has no errors array)
- Add skipped_count to all BulkActionResult construction paths
- Add dry_run support to BulkActionRequest type
- Transform backend results[] to frontend errors[] in non-streaming path
- Remove unused errors variable in streaming fallback path
