The Audio menu's settings now behave as the original's (docs/engine/front-end.md).

• At boot, 0x80070c24 (called from show_still while the boot stills show) tries both cards. 0x800702d8 copies the last record saved (word 3, its bit in word 1) at +0x2c/+0x30/+0x34 into the state's +0x0c/+0x10/+0x14. Progress::restore_audio does the same over the Cards, and the app calls it before the legal screen.
• A new game no longer resets them. 0x80091a44, the new game's reset, clears only +0x40..+0x46 and the two bar arrays; the volumes stay. Before, the port replaced the whole state with Progress::default(), so Start Game or Activities after the Audio menu put the volumes back to 90/100. Progress::new_game keeps the settings.
• Test (tests/card.rs, settings_come_back_at_boot): a record with music 40, effects 70 and mono, stored on a scratch card, comes back at boot and survives new_game. No card gives nothing.
