fix: fastfetch logo stretching and centering, slideshow COSMIC update

- Remove explicit width/height from fastfetch logo config so kitty auto-sizes without stretching
- Remove stray keyWidth:20 from first section footer that shifted bottom border right
- Add 4 dashes to first footer to match header width (71 chars each)
- Update slideshow COSMIC text and welcome app copy
