Krzysztof Cieślik 331813e5de fix(ui): stop dropping cached tiles when zooming away and back (#2196) (#2323) ...

- Retain tiles of on-screen pages at both eviction sites in
  crates/ui-egui/src/canvas.rs, so a pan or zoom that moves the viewport no
  longer discards tiles that were rendered sharp moments earlier.
- Stop dropping a zoom's tiles when zooming out far enough shows the page
  whole; that made returning to a visited zoom a cold miss, which re-blurred
  the page and re-interpreted it once per tile.
- Bound older-zoom retention by bytes (TILE_BYTES) as well as by count
  (OLD_TILES): a tile of a large scan can be 4096 squared, about 67 MiB, so a
  count alone ran past the tile allowance.
- Add returning_to_a_visited_zoom_reuses_its_cached_tiles, which fails on the
  reverted fix, and cite both view tests in view.deep-zoom-tiles; the entry
  stays partial because the 8192 px-per-side cap is untouched.
