chore(branding): update fastfetch ASCII icon and fix branding typos

- Optimized assets/branding/icon.txt with multi-color placeholders for fastfetch.
- Updated config/fastfetch/config.jsonc to use the new multi-colored icon.
- Added icon and svg branding assets to modules/home/theme-files.nix.
- Fixed 'Nnomarchy' typo to 'Nomarchy' and updated branding paths in several scripts.
- Corrected screensaver and welcome scripts to use the centralized branding assets.
