fix(engine): eliminate panics, fix dismiss hit-test scope, guard home respawn

Browse Source 
CR-2: dismiss_modal_on_scrim_click now queries only the target scrim's
      Children rather than all ModalCard entities globally. Prevents
      dismissing the wrong scrim when two overlapping modals are open.

CR-5: handle_home_draw_mode_buttons and handle_home_difficulty_toggle
      now check other_modal_scrims.is_empty() before the despawn+respawn
      cycle, preventing a concurrent second ModalScrim in the same frame.

H-1:  solitaire_core::game_state — replaced all panicking piles[&key]
      index accesses with safe .get().ok_or(MoveError::InvalidSource)?,
      .get().is_some_and(...), or .get().and_then(...) in draw(),
      check_auto_complete(), next_auto_complete_move(), foundation_slot_for().

H-5:  input_plugin end_drag and touch_end_drag — replaced piles[&target]
      with .get(&target).is_some_and(...) so missing pile types reject the
      move rather than panicking.
