Phase 4: backups + import/export config

ConfigStore.SaveAsync now snapshots the previous config to %ProgramData%\WebhookServer\backups\config-<timestamp>.json before overwriting, retaining the last 30. Failures are silent so a backup-write hiccup never blocks an actual save. Three new admin pipe ops: - list-backups: returns newest 50 entries with timestamps and sizes - restore-backup: takes a fileName, refuses path-traversal chars, loads the named backup over the live config (which itself triggers a fresh backup of the current state via the SaveAsync hook) - import-config: replaces the current config with a GUI-supplied ServerConfig, merging encrypted secrets where the GUI didn't supply new plaintext GUI File menu items are wired: - Import config: file picker -> ImportConfigAsync - Export config: SaveFileDialog writes the current config as JSON - Backups: dynamic submenu auto-refreshed when opened, listing backups with timestamp + size; click to confirm-and-restore Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
