Two related brand-asset cleanups bundled per request:
portal-shell — header logo:
- Replace `apf-small.png` (a 7.6 KB raster wrapped through sharp from
the original PNG-in-SVG file) with `apf-logo.svg`, an actual
vector 1024×1024 export (2.1 KB). Sharper at any density, smaller
payload, no rasterisation artefacts when the header zooms.
- `header.html` swaps the `<img src=…>` accordingly.
- The wide-format `apf-portal.svg` stays in place for future
surfaces (login splash, etc.).
portal-admin — favicons + PWA manifest:
- Mirror portal-shell's PR #84 setup. Copy the six favicon image
assets (favicon.ico, favicon.svg, favicon-96x96.png,
apple-touch-icon.png, web-app-manifest-{192,512}.png) into
`apps/portal-admin/public/favicons/`. Single visual identity
across the two apps.
- Customise `site.webmanifest`: `name: "APF Portal Admin"`,
`short_name: "Admin"`. PWA install banners and home-screen
icons read the right app name when admin is installed
standalone. Icon entries + theme-color + display stay identical
to portal-shell.
- Wire `<link>` tags in `apps/portal-admin/src/index.html` mirroring
portal-shell's, plus `<meta name="theme-color">`.
- Remove the now-obsolete top-level `apps/portal-admin/public/favicon.ico`
(replaced by the entry under `favicons/`, referenced via
`<link rel="shortcut icon">`).
Verified: `nx run-many -t lint test build --projects=portal-shell,
portal-admin` green; both `dist/.../browser/{en,fr}/favicons/` ship
the seven expected files; admin manifest contains "APF Portal Admin";
admin `index.html` has the right `<link>` block.
