Fix dynamic theming: enable filesystem writes and add theme switching

- Add LD_LIBRARY_PATH and ILLOGICAL_IMPULSE_VIRTUAL_ENV to quickshell service
- Set ProtectSystem=false to allow color generation scripts to write files
- Fix MaterialThemeLoader to properly detect file changes with onFileChanged
- Add switchwall-wrapper.sh to source environment variables dynamically
- Fix light/dark mode buttons to use Process with current wallpaper
- Add --choose flag to switchwall.sh for wallpaper selection dialog
- Add IPC commands 'dark' and 'light' for console theme switching
- Update keybinds: Ctrl+Super+T (choose), Ctrl+Super+Shift+T (random)
- Fix terminal color application in applycolor.sh
