fix(badges): render QR code on badge front when show_qr_front is set

Fixed three issues in ae_comp__badge_obj_view.svelte:
1. Bug: {#await} block used src={qr_data_url} (the Promise) instead of src={result}
   (the resolved data URL) — QR image never displayed correctly on badge front.
2. Layout: .special div had no flex context; added flex-row + items-end so the QR
   sits at the bottom-right of the body section via ml-auto.
3. Cleanup: removed dead second QR block that awaited event_badge_qr_id_get_promise
   (always null), which could never render.

Also marks CRUD v2 refactor as complete in TODO__Agents.md.

+- ~~**CRUD v2 Refactor:** Finalize retirement of `Element_ae_crud_v2.svelte` in favor of V3 Editor.~~ ✅ Done (2026-03-05) — all non-IDAA usages migrated; IDAA had zero usages.
 - **Temp Cleanup:** Auto-removal of native `.tmp` files older than 24h.
 - **`window.print()` for badge print button:** Wire the existing `handle_print_badge()` to trigger `window.print()`. Browser print works well across Chrome/Chromium/Firefox — no Electron needed.
 - **Input Field Audit:** Several input fields are missing `name`/`id` attributes or `data-testid`. Known examples: badge override fields in `ae_comp__badge_obj_view.svelte`; template name input in `ae_comp__badge_template_form.svelte`. Matters for: accessibility, autofill, label associations, and test targeting. (For tests, use `getByLabel()` rather than `input[value*=...]` which only checks the HTML attribute, not the Svelte-bound DOM property.)
