perf: shrink map marker payload and extend vendor chunking

C (marker): Reuse the existing ~24 KB logo.png for the "you are here"
map marker instead of the 2.9 MB user-location.png (byte-identical copy
of logo-sticker). Removed the unused 2.9 MB PNG from public/images,
cutting deploy/APK size. Same artwork, ~99% smaller payload.

B (chunking): Extend the existing manualChunks in vite.config.ts to
split the largest page-specific libraries into their own vendor chunks
(hls.js, html5-qrcode, recharts) so they load only on the routes that
use them. Capacitor single-bundle branch and React core grouping left
untouched.
