Normalize remaining ~/.local/share/omarchy refs in bin/

Missed in the previous pass:
- bin/omarchy-launch-screensaver: alacritty/ghostty config paths
- bin/omarchy-refresh-applications: source paths for icons and .desktop
- bin/omarchy-refresh-config: docstring/comment references

Still NOT touched (intentional):
- bin/omarchy-reinstall-git: stages '~/.local/share/omarchy-{old,new}' for
  the script-mode upgrade dance; needs redesign for package mode.
- bin/omarchy-dev-add-migration: uses 'cd ~/.local/share/omarchy' to read
  a git log; only meaningful in dev mode.
- bin/omarchy-install-browser:69: writes a string into a chromium config file.
- install/helpers/errors.sh:125: boot.sh relaunch (separate redesign).
