Erich Blume 9829a6f971 Add screen lock and idle management to ringtail (#211)
## Summary
- Configure **swayidle** to lock screen (swaylock) after 15 minutes of inactivity
- Turn off display (DPMS) after 60 minutes, auto-restore on activity
- **swaylock** themed with Catppuccin Macchiato to match existing Sway config
- Add `Mod4+l` keybinding for manual screen lock
- Add PAM service for swaylock authentication
- Disable system suspend/hibernate entirely (workstation should never sleep)

## What changes
All changes in `nixos/ringtail/configuration.nix`:
- `security.pam.services.swaylock` — required for swaylock to authenticate on NixOS
- `systemd.sleep.extraConfig` — blocks all sleep/hibernate modes
- `programs.swaylock` (home-manager) — lock screen appearance config
- `services.swayidle` (home-manager) — idle timeout daemon with lock + DPMS events
- New keybinding `Mod4+l` for manual lock

## Deployment and Testing
- [ ] `mise run provision-ringtail`
- [ ] Verify swayidle is running: `systemctl --user status swayidle`
- [ ] Test manual lock with `Super+l`
- [ ] Verify display DPMS off after idle (can lower timeout temporarily to test)
- [ ] Confirm machine does not suspend: `systemctl status sleep.target`
