Phase 3 step 4b of the UX overhaul. Same shape as the Confirm modal
conversion (3f922ed): replace plain "Press N for new game" /
"Press G to forfeit" text hints with real Button entities, hover
and press feedback included.
The audit flagged the Game Over overlay as the second instance of
the "feels like a debug panel" problem. Players had to know the
hotkeys to escape the screen — there was no clickable affordance.
Modal contents:
- Header: "No more moves available"
- Body: "Final score: {N}" (TYPE_BODY_LG, TEXT_PRIMARY)
- Actions:
Undo (Secondary, hotkey "U") — left
New Game (Primary yellow, hotkey "N") — right
The G/forfeit hint is dropped from the modal because:
1. Forfeit is handled globally by `input_plugin::handle_forfeit`
(which works whether the modal is up or not).
2. The proposal calls for replacing the toast-countdown forfeit
flow with its own modal in step 4c (next commit).
A new `handle_game_over_button_input` system mirrors the keyboard
handler for clicks. Existing N/Esc and U accelerators continue to
work via the original `handle_game_over_input`.
The `game_over_screen_text_content` test is updated to assert the
new button-label / hotkey-chip strings instead of the prior prose
hints. All 797 tests still pass.
