v0.4.2 — Pinned headers & layout polish

UI
• Restore backup picker: pinned column headers, wider Backup column, right-aligned Size
• INI restore picker: matching pinned header with "INI Backup" / "Size" columns
• All picker highlight colour changed to yellow for better visibility
• Main menu entries shifted 1 left; INI submenu entries aligned with main menu
• Spacer row between list content and status bar on all screens
• Non-blocking info dialog for backup-in-progress (no button, auto-replaced)
• Split-layout backup picker — file list on left, live GVAS metadata on right
• ► pip highlight replaces background bar on all menus
• Blank separator lines for visual grouping in menus
• "Set Subnautica 2 location" and "Set backup location" menu entries
• Context-aware header path — title bar shows the relevant file location for the current menu/screen

Layout
• Backup column widened from 30→38 chars; header/data total widths matched
• Size header right-aligned above file-size values in both restore pickers
• INI submenu header changed to cyan, shifted 3 right

Backup
• No intermediate spinner page — info popup followed by summary dialog
• tar.gz backup format — one archive per backup event

Configuration
• Persistent app.ini — save folder and backup location survive sessions
• Config stored in platform-standard directory (AppData/Local on Windows)
• UE5 .ini backups stored in backups/ue5/ under the backup root
• Logs moved to data_local_dir/NotAlterra/logs/
• Stale config.ini auto-removed from prior versions
