fix(ui): fade or unfade browser row dynamically when visibility toggles (#9953) (#9967)

- In entry_row (crates/ui-egui/src/browser.rs), use live  rather than cached  for the  property
- Ensures eye toggle dynamically fades or unfades rows for sketches and bodies without requiring a cache rebuild
- Add regression test in browser_card_tests
