feat: leads re-enable flow — detect removed leads on scan + Remove/Restore buttons

- QR scanner (single + multi): detect previously-removed leads via IDB enable flag;
  route to 'reenable' state instead of duplicate error; offer Re-activate button
- API fallback: if create fails and no IDB record, search API for disabled tracking
  record by event_exhibit_id + event_badge_id (adds qry_badge_id param to
  search__exhibit_tracking)
- Lead detail page: Replace raw enable checkbox with Remove Lead (two-click confirm,
  navigates back after) and Restore Lead card (shown when enable is falsy)
- Fix flash of disabled records in leads list: filter !enable in both filtered_lead_li
  derived and local IDB fast-path in handle_search_refresh
- eslint.config.js: disable svelte/no-navigation-without-resolve (no base path configured)
- Also includes _random field annotation cleanup (db_events, ae_types), iframe layout
  fixes, badge view tweaks, test updates, and doc updates from prior session

 **Symptom:** Providing a string ID in a search body that the backend maps to an integer can result in **Zero Results** if the underlying view expects a string.

 2.  **Headers:** Pass `headers: { 'x-account-id': ... }` manually to provide context for Auth validation.
 3.  **Isolation (IDAA):** Due to specific bugs in the IDAA module, it has been temporarily isolated to a legacy V2 search function (`qry_ae_obj_li__event_v2`) using `default_qry_str` for text searching, while the main module continues to use the V3 implementation.
