fix(ui-e2e): tighten Phase 29 effect tracking + radio wiring

Run #217 surfaced three independent bugs that survived the first
fixup pass:

1. `visibleHighBitCount` masked the id with `(prim.id >>> 0) & 0xf…`,
   but JS bitwise AND always returns a signed int32 — the mask had
   to be re-converted with `>>> 0` AFTER the AND, not before. Result
   was always 0 on the previous run, masking the next two bugs by
   making the persistence test's high-bit-count assertions a
   tautology.
2. `applyVisibilityState` was wrapped in `untrack`, so the
   `toggles.X` reads inside `computeHiddenIds` / `computeFogCircles`
   never landed in the effect's dependency set — toggling fog or any
   marker / group / kind flag did not re-run the effect, so the
   renderer never received the new hide / fog input. Explicit
   `void toggles.X` reads now live at the top of the effect so every
   key is tracked synchronously.
3. The wrap-mode radios fired on `onchange`, which Svelte 5
   suppresses on a re-activation of an already-checked input — the
   Playwright `.click()` flake on the second wrap test reflected the
   missed event. Switched to `onclick` and short-circuited when the
   target mode is already active.
