replace the last use of the old apply client with the SSA client

[metlos]

This makes the toolchainclusterresources controller use the SSA client instead of the obsolete apply client.

Summary by CodeRabbit

• Refactor
  • Improved resource application mechanism with enhanced label management and field-level consistency enforcement during reconciliation cycles.
  • Streamlined internal resource management pipeline for more reliable toolchain cluster resource handling.

Walkthrough

A new generic ApplyAll function is introduced for applying slices of client objects. The SSAApplyClient.Apply method delegates to this generic function. The Reconciler struct gains a FieldManager configuration field, and the controller's reconciliation flow switches to using the new generic apply mechanism with explicit label handling.

Changes

Cohort / File(s)	Summary
Controller Configuration & Reconciliation controllers/toolchainclusterresources/toolchaincluster_resources_controller.go	Added public FieldManager field to Reconciler struct. Updated reconciliation logic to create SSA apply client using the field manager and switched from ApplyUnstructuredObjectsWithNewLabels to ApplyAll with EnsureLabels(newLabels). Added minor formatting.
Controller Tests controllers/toolchainclusterresources/toolchaincluster_resources_controller_test.go	Updated test setup to initialize Reconciler.FieldManager to "testOwner".
SSA Client Core pkg/client/ssa_client.go	Introduced new generic function ApplyAll[T client.Object] for iterating and applying object slices. Refactored SSAApplyClient.Apply to delegate to the new generic function.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Generic function logic: Verify that the ApplyAll[T] function correctly implements the iteration pattern and error handling for any client.Object type.
• Delegation correctness: Ensure SSAApplyClient.Apply properly delegates to ApplyAll without behavioral changes.
• Label handling transition: Review the shift from ApplyUnstructuredObjectsWithNewLabels to ApplyAll with EnsureLabels to confirm equivalent label enforcement.
• FieldManager configuration: Verify the new FieldManager field is properly initialized and used in SSA client creation.

Poem

🐰 A generic hop through apply and slice,
Where objects dance in loops precise,
Field managers guide the way,
Refactored code saves the day!

113-114: Test field manager wired correctly

Thanks for plumbing the test owner string through prepareReconcile; this keeps the SSA client behavior exercised end-to-end.

241-252: ApplyAll refactor keeps semantics intact

Nice extraction—ApplyAll centralizes the iteration logic without changing how ApplyObject is invoked.
