Grab-bag of UX gaps from audit-pass-#2 + #3. Each one is a small,
focused fix; bundled because they touch different surfaces.
- Popover: collisionPadding={16} + responsive
w-[min(calc(100vw-2rem),18rem)] so popovers stop clipping past the
viewport on iPhone 12 portrait.
- public/manifest.json (was missing) + manifest reference in
layout.tsx — PWA installability now works; icons (192/512/512-
maskable) were already present.
- Admin webhooks page: 4 silent `// ignore` catches in load/delete/
toggle/regenerate replaced with toast.error / toast.success. Users
no longer see a stale list with no feedback when an op fails.
- Portal document-download button: blocking alert() → toast.error().
- src/app/(dashboard)/error.tsx: branded error boundary with retry +
back-to-dashboard, replacing Next.js's default uncaught-error UI.
- GDPR export modal: refetchInterval was a flat 5s while the modal was
open. Switched to a function that only polls (every 15s) when a job
is actually pending/building; settled exports stop polling entirely.
- client-yachts-tab empty state gains a CTA wired to the existing
Add-yacht dialog, instead of just saying "No yachts".
