feat: leads QR scanner — Auto/Multi modes, 4-mode fancy selector, UX polish
Scanner modes (now 4, persisted per exhibit): - Rapid: confirm tap → auto-reset (existing, fixed) - Qualify: confirm tap → navigate to lead detail (existing, fixed) - Auto: badge found → auto-add immediately, no confirmation tap needed - Multi: BarcodeDetector batch scan → responsive grid of confirm cards Multi scanner (new ae_comp__lead_qr_scanner_multi.svelte): - Native BarcodeDetector API (Chrome/Edge/Safari 17+); Firefox fallback message - 16:9 viewfinder with corner guides + "Align up to 4 badges flat" overlay - Capture Batch tap → up to 8 QR codes detected in one frame - Per-card states: loading skeleton, ready (Add/Skip), blocked (opt-out), already-captured (View/OK), adding spinner, success (auto-fade), error - Add All (N) bulk action; cards fade+scale out smoothly on dismiss Mode selector (ae_tab__add.svelte): - Replaces Rapid/Qualify toggle with collapsible 4-mode fancy select - Trigger shows active mode icon (color-coded) + name + description - 2×2 options grid expands on tap, closes on selection QR scanner element (element_qr_scanner_v3.svelte): - object-fit: cover eliminates 4:3 camera letterbox dead zone - 7-second start timeout with actionable error message - Starting/error overlays with high-contrast styling - Try Again button with RefreshCw icon Style guide updated: icon+text button rule (§8), btn/preset-filled workaround (§12) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
