fix(client): address PR #62 review suggestions — polish pass

- interaction_list.gd: skip queue_redraw() when position unchanged (Tyre #4)
- time_display.tscn: widen bounding rect 154x44→184x54, add clip note
  for #314 wireframe (Tyre #3)
- test_time_display_sprint17.gd: document private state access pattern
  in header (Tyre #5), add upper bound assertion for D-031 1439 max (Hoshe #6)

 ## Implementation: client/ui/time_display.gd — draw-based Control at InsertOverlay/TimeDisplay.
 ## Format function: Constants.format_game_time(time_of_day: int) -> String (extracted for
 ## testability from time_display.gd:46 inline Constants.format_game_time(tod)).
+##
+## Private state access: Tests read _time_str, _phase_str, _day_str, _has_data directly
+## because time_display.gd is draw-based (no Label nodes to inspect). This is an accepted
+## test pattern for draw-based UI — the private vars ARE the rendered output contract.
+## If the rendering approach changes (e.g. to Label nodes), these tests should switch to
+## reading Label.text via public node paths instead.
