Title: Music, Sound & UI Polish

New tunes, better sound feedback, and a fresh coat of ReapCo-approved UI polish!

• Added title music and a hub music loop.
• Added a dedicated, tabbed Settings screen accessible from the lobby and pause menus.
• Added separate Music and SFX volume controls, with saved volume and look settings.
• Added UI sounds for buttons, settings tabs, inventory, machines, and standalone containers.
• Added four randomized pickup sounds, heard only by the collecting player.
• Routed punch sounds through the SFX mixer and synchronized the punch whoosh with its animation.
• Improved enemy sound attenuation so distant footsteps don’t sound like they’re right beside you.
• Updated crafting, recycler, and generator UI styling.
• Improved crafting bench and upgraded machine layouts, container spacing, and scrolling to reduce HUD overlap.
• Restyled Mission Select to match the other menus, with a scrollable station list and clearer selection states.
