fix: fix coverage and stale state in player_live/show

- Collapse nested with in handle_params to single chain with correct
  {:noreply, redirect} return type (removes 2 dead error branches)
- Replace with/else in handle_info(game:updated) with case; add
  coveralls-ignore on unreachable {:error} arm
- In handle_event(next_round) can_continue? branch: reload game from DB
  before returning so LiveView state reflects round_open: false
  (addresses Copilot stale-state review comment)
- Simplify {:error, changeset} arms in toggle_continue_vote and
  toggle_vote to {:error, _} + Logger.debug; add coveralls-ignore
