+ central PWA: real PNG icons, SW registration, scope=/
- All `fn ($r) =>` and `fn (Type $r) =>` replaced with $record (Filament v5
injects callback params by name; $r resolved to nothing)
- /pwa/admin-{192,512}.png — generated on-the-fly with GD + DejaVuSans-Bold
- /pwa/admin-icon.svg — vector favicon
- /admin-sw.js — service worker (cache shell, network-first elsewhere)
with Service-Worker-Allowed: / header
- Manifest scope=/ + start_url=/admin → install prompt fires on Chrome/Edge/Safari
- BODY_END render hook registers SW on central panel
