feat: add configurable auto-restart on client auto-disable

Add a configurable option to restart Xray when clients are auto-disabled and persist disable actions.

Changes include:
- New setting restartXrayOnClientDisable (default true), getters/setters in SettingService, UI toggle in general settings, and translations for multiple locales.
- AddTraffic signature updated to return a third bool (clientsDisabled). disableInvalidClients now calls Xray API to remove users, marks client_traffics.enable=false, updates inbound.Settings JSON so clients appear disabled in stored settings, and returns appropriate counts/errors.
- XrayTrafficJob now checks the clientsDisabled flag and restarts Xray when the setting is enabled (with fallback to mark Xray as needing restart on failure).
- XrayService.GetXrayConfig call adjusted to ignore AddTraffic returns.
- Subscription generation (subService/subJson/subClash) no longer filters clients by their enable flag when matching subId.
- Minor fixes: check_client_ip_job now checks scanner.Err and improved API error handling/logging.

These changes ensure auto-disabled clients are propagated to Xray and the stored inbound settings, and provide an option to restart Xray automatically after auto-disable events.
