Sicherhaven cf21e0a58c perf: add memCacheWidth/memCacheHeight to all thumbnail images ...

All CachedNetworkImage instances in list/card contexts now decode at
2x rendered size instead of full resolution. A 3000x2000 event photo
previously decoded to ~24MB in GPU memory even when shown at 96px —
now decodes to <1MB.

Affected screens (16 CachedNetworkImage instances total):
- home_screen.dart: hero (800w), top card (300w), stacked (192w),
  horizontal (440x360), full-width (800x400), search (112x112),
  filter sheet (160x160), type icons (112x112)
- home_desktop_screen.dart: mini (128x128), grid (600x280), horiz (600x296)
- calendar_screen.dart: event card (400x300)
- profile_screen.dart: avatar (size*2), event tile (120x120)

learn_more_screen.dart intentionally unchanged — full-res for detail view.

Estimated memory reduction: ~500MB → ~30MB for a typical home screen.
