Add a hot-apply layer that computes a diff between the old and new
generated config and applies only the changed parts through the Xray
gRPC HandlerService and RoutingService, avoiding a full process restart
whenever possible. A restart is still performed when sections that have
no reload API (log, dns, policy, observatory, ...) actually change.
Key additions:
- internal/xray/hot_diff.go: ComputeHotDiff with canonical-JSON
comparison (sorted keys, null=absent, full number precision) so UI
reformatting never triggers a spurious restart
- internal/xray/api.go: AddOutbound/DelOutbound, ApplyRoutingConfig,
GetBalancerInfo, SetBalancerTarget, TestRoute gRPC wrappers
- internal/web/service/xray.go: tryHotApply, ensureAPIServices,
GetBalancersStatus, OverrideBalancer, TestRoute service methods
- internal/web/controller/xray_setting.go: balancerStatus,
balancerOverride, routeTest API endpoints
- frontend: BalancersTab live-status/override columns, RouteTester
component, Restart button removed (Save now hot-applies)
- balancer-helpers.ts: syncObservatories never creates observatory
sections for random/roundRobin balancers (no reload API → restart)
- i18n: balancerLive/Override/routeTester keys added to all 13 locales
