Use bundled logo from public/ instead of the API

Header, footer and og:image now read public/images/logo.png via
LOGO_SRC in config.ts. The API's /website/favicon returned another
business's mark, so getFavicon()/BrandAssets are removed and the tab
icon is the bundled favicon.png. Footer logo is now 70px like the
header (108px was sized for the old square mark; the new 200x48
wordmark would be 450px wide).

-- Logo/favicon: `getFavicon()` in `src/lib/api.ts` reads
-  `GET /tenants/moalem.shop/website/favicon` — the documented single source —
-  and `Header.tsx`/`Footer.tsx`/`generateMetadata()` in `layout.tsx` all use
-  it, falling back to the bundled `/images/logo.png` / `/favicon.png` only
-  when the API field is null. **As of 2026-09-06 the dashboard has a logo/
-  favicon uploaded, but it's the wrong business's** (a home-appliances store's
-  mark, not موبایل معلم) — the wiring is correct and will pick up the right
-  asset automatically the moment it's replaced in the dashboard; don't
-  "fix" this by hardcoding the local fallback again.
-- Header (desktop) logo renders at `h-[70px]`; footer logo stays at
-  `h-[108px]` (3x the original `h-9`/36px, on request) — the two were sized
-  independently, on request, so don't assume they should match. If the wrong
-  logo above still looks small at either size, it's because that specific
-  PNG has a lot of baked-in transparent padding around the mark —
-  `object-contain` can't fix that, only the replacement asset can.
+- Logo: **bundled, not from the API** — `public/images/logo.png` (200x48
+  wordmark, supplied by the business), referenced via `LOGO_SRC`/`LOGO_WIDTH`/
+  `LOGO_HEIGHT` in `src/lib/config.ts` by `Header.tsx`, `Footer.tsx` and the
+  og:image in `layout.tsx`. This was an explicit decision (2026-09-20): the
+  API's `/website/favicon` returned another business's mark, so
+  `getFavicon()` was removed entirely — don't re-add it. Tab icon is the
+  bundled `public/favicon.png`. To change the logo, replace the file (keep
+  the same name; update `LOGO_WIDTH`/`LOGO_HEIGHT` if its shape changes).
+- Header (desktop) and footer logos both render at `h-[70px] w-auto`.
