chore: remove dead Test/TestSuite v3 code

[vsukhin]

Test and TestSuite (tests.testkube.io) are deprecated CRDs, retained only so existing cluster resources are not garbage-collected. Nothing serves or reconciles them: no API routes, no CLI commands, no controller, no client. This removes the surface that has no callers at all.

• delete pkg/tcl/mappertcl/tests (no importers)
• delete pkg/mapper/testworkflows/kube.go; all three roots (MapTestKubeToTestWorkflowKube, MapTestSuiteKubeToTestWorkflowKube, MapExecutorKubeToTestWorkflowTemplateKube) were unreferenced, leaving the whole file orphaned
• drop the unused crd.Template consts and their .tmpl files, keeping webhook, webhooktemplate and testtrigger
• drop vestigial testsuitev3/testsv3/testsourcev1 AddToScheme calls in pkg/triggers/watcher.go; no informer for those types exists
• delete the typed tests/v2 and tests/v3 clientsets and their fakes. v2 was additionally broken: tests.testkube.io/v2 was never registered in the scheme builder, so any call would have failed at request time.

The CRDs, api/tests/v3 and api/testsuite/v3 are left untouched, along with the sub-types (Variable, ArtifactRequest, EnvReference, GitAuthType, ArgsModeType) that TestWorkflow v1 and TestTrigger v1 embed.

Pull request overview

This PR removes unused/dead code paths related to deprecated tests.testkube.io Test/TestSuite v3 (and related) surfaces, including orphaned mappers, clientsets, and CRD templating assets, leaving only the still-supported trigger/webhook CRD template flow and watcher scheme registrations.

Changes:

• Removed unused scheme registrations and Kubernetes watcher wiring for deprecated Test/TestSuite/TestSource types.
• Deleted unreferenced mapping/helpers (pkg/tcl/mappertcl/tests, pkg/mapper/testworkflows/kube.go) and deprecated CRD template assets/constants.
• Removed typed operator clientsets (and fakes) for tests.testkube.io v2/v3 and updated the versioned clientset accordingly.
