fix: correct Noctalia widget monitor layout

[CollieIsCute]

Summary

• parse hyprctl monitor JSON inside jq so x-position sorting actually applies
• account for rotated outputs when deriving desktop widget coordinates on the right monitor
• keep lockscreen widget coordinates in Noctalia's expected unrotated reference space
• clear local stale Noctalia lockscreen state so config fallback is active on this machine

Verification

• chezmoi execute-template < home/dot_config/noctalia/20-widgets.generated.toml.tmpl
• chezmoi apply -v /home/collie/.config/noctalia/20-widgets.generated.toml
• noctalia config validate /home/collie/.config/noctalia
• noctalia config validate /home/collie/.config/noctalia/20-widgets.generated.toml
• noctalia config validate
• chezmoi diff /home/collie/.config/noctalia/20-widgets.generated.toml
• restarted noctalia and confirmed it is responding with noctalia msg status

Notes

• Desktop widget idle/media visibility settings are intentionally unchanged: show_when_idle remains false, hide_when_no_media remains true.
• A full chezmoi apply dry-run shows unrelated destination drift under ~/.config/opencode/skills; this PR does not touch those files.
