Ryan Hughes 5683750b29 Add pacman --overwrite for transition paths; fix mimeapps/HEY and PAM idempotency
Four corrections to the omarchy-settings transition:

- bin/omarchy-update-system-pkgs: pass --overwrite for the 13 paths
  omarchy-settings now owns. Existing Omarchy installs would otherwise
  fail pacman conflict checks on the upgrade that ships the package
  (the files exist as unowned filesystem entries from the previous
  install scripts). The flags are no-ops once the transition release
  is everyone's baseline; remove then.
- config/mimeapps.list: drop the HEY.desktop mailto mapping. HEY.desktop
  is generated by install/packaging/webapps.sh at install time, not
  shipped under applications/, so it isn't valid for a fresh /etc/skel
  user before the installer runs.
- install/config/mimetypes.sh: add 'xdg-mime default HEY.desktop
  x-scheme-handler/mailto' as a runtime op since the mapping no longer
  lives in mimeapps.list.
- install/config/increase-lockout-limit.sh: delete existing
  pam_faillock.so authsucc lines before re-adding, so re-running the
  installer doesn't duplicate the authsucc entry in
  /etc/pam.d/sddm-autologin.

# The faillock.conf side ships via the omarchy-settings etc-overrides
# (deny = 10). The two PAM file edits below remain a script because
# /etc/pam.d/system-auth and /etc/pam.d/sddm-autologin are upstream-owned
# and the changes are insertions, not full-file overrides.
# Increase lockout limit to 10 and decrease timeout to 2 minutes
