Restructures the Home overlay per docs/ui-redesign-2026-07.md Phase B:
- Continue card (mode / elapsed / score) when a game is in progress;
clicking returns to the table
- Hero New Game replays the persisted Settings::last_mode (new field,
serde-default Classic) with one tap; locked modes fall back to Classic
- Deal options (draw 1/3, winnable-only, difficulty tiers) move into a
disclosure under the hero — off the Home top level (decision 2)
- Compact symmetric 2x3 mode grid; descriptions on wide viewports only
- Stats strip moves to the bottom (right pane on wide)
- Two-pane body on wide viewports (>= 1000 logical px) via new
ui_modal::spawn_modal_sized (default card stays 720 px)
- Cancel becomes "Back to table" and only renders while a live
(un-won) game exists
10 new home_plugin tests; all 936 engine tests + clippy green.
