fix: normalize script matching to handle underscore vs hyphen differences

- Add normalizeId helper to compare local filenames with script slugs/names
- Include install_basenames from install_methods for robust matching
- Fix false 'Not Downloaded' status for PVE Host scripts like 'PVE LXC Execute Command'
- Update DownloadedScriptsTab and ScriptsGrid to use normalized comparisons
- Resolves issue where scripts with underscores in filenames (e.g., pbs_microcode.sh)
  weren't matching JSON slugs with hyphens (e.g., pbs-microcode)
