Current Behavior

From e2e nightly run https://github.com/Kong/kubernetes-ingress-controller/actions/runs/12425611716, e2e test case TestKonnectConfigPush always fails. The test could not find service from Konnect API:

 helpers_test.go:532: Fetched config from "https://us.kic.api.konghq.tech/kic/api/control-planes/****", started at 2024-12-20T04:43:18Z, duration 29.067824ms
    helpers_test.go:541: 0 services found, expected 1

Expected Behavior

Test passes where services could be found on Konnect.

Steps To Reproduce

Run e2e test case TestKonnectConfigPush.

I think the code here may cause client not correctly initialized in Konnect config syncer:

kubernetes-ingress-controller/internal/manager/run.go

Line 284 in 3dce2d3

go setupKonnectAdminAPIClientWithClientsMgr(ctx, c.Konnect, clientsManager, setupLog)

When the konnect client is not created before we setup Konnect config syncer, the syncer will receive a nil client and does not have chance to set the correct client:

kubernetes-ingress-controller/internal/manager/run.go

Lines 291 to 300 in 3dce2d3

	konnectConfigSynchronizer, err := setupKonnectConfigSynchronizer(
	ctx,
	mgr,
	c.Konnect.UploadConfigPeriod,
	kongConfig,
	clientsManager,
	updateStrategyResolver,
	configStatusNotifier,
	metricsRecorder,
	)

Where setupKonnectConfigSynchronizer uses the konnect client from the client provider to initialize the config syncer

kubernetes-ingress-controller/internal/manager/setup.go

Line 521 in 3dce2d3

clientsProvider.KonnectClient(),

I changed the syncer to make it use the client got from clientProvider each time when it syncs to Konnect.
