chore: remove orphaned legacy files and move QR scanner to elements/

- Trashed 10 unreferenced files: core .legacy types, bak files, element_modal_v1, element_websocket_v2, AE_MetadataFooter_not_ref, element_qr_scanner_v2
- Removed empty placeholder dirs: ae_db/, hooks/
- Moved element_qr_scanner_v3.svelte from lib root into elements/
- Updated 2 import paths for QR scanner (badges + leads)
