fix(gastown): repair malformed patch files for nixos-rebuild

- Remove 'index 0000000..1111111' lines that made patches appear as new files
- Fix hunk line counts in several patches
- Add missing leading spaces to blank context lines
- Temporarily disable statusline optimization patch (needs regenerating)
