Config Checkpoints dialog + daily auto-checkpoint; drop installer GUI launch

Three fixes: 1. Config Checkpoints submenu replaced with a proper dialog. Lists checkpoints with timestamp/size/filename, has a "Take Checkpoint Now" button, and a "Roll Back" button that becomes enabled when a row is selected. The previous click-a-menu-entry-immediate-restore flow was too easy to fire by accident. 2. New CheckpointScheduler BackgroundService creates a checkpoint at midnight every day. Combined with the existing auto-on-save snapshots, this guarantees a daily rollback point even if the config wasn't edited that day. A new "create-checkpoint" admin op plus AdminPipeServer.CreateCheckpoint helper does the actual file copy; both manual (via the dialog) and the scheduler use it. 3. Installer: drop the post-install "Launch Webhook Server" wizard step. It tried to launch the GUI un-elevated, which fails because the GUI's manifest is requireAdministrator. The Start Menu shortcut handles elevation correctly, so the user can launch from there. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
