Add kstatus-compatible conditions to CR status fields

[Copilot]

Implements standardized condition reporting for all Custom Resources to enable status observability via kstatus.

Changes

API Types

• Added Conditions []metav1.Condition to all status structs (HarborConnection, Project, Registry, User, Member)
• Conditions follow Kubernetes API conventions with standard types: Ready, Reconciling, Stalled

Controllers

• All reconcilers now set conditions at key points:
  • Ready=False + Stalled=True on connection failures, invalid specs
  • Reconciling=True during create/update/adopt operations
  • Ready=True + Reconciling=False + Stalled=False on successful reconciliation
• Common reasons: ReconcileSuccess, ReconcileError, Creating, Updating, ConnectionFailed, InvalidSpec

Helpers

• New internal/controller/conditions.go with SetCondition, GetCondition, RemoveCondition
• Convenience functions: SetReadyCondition, SetReconcilingCondition, SetStalledCondition
• Handles timestamp updates only on status transitions

Example

After reconciliation, resources expose standard conditions:

status:
  harborProjectID: 123
  conditions:
  - type: Ready
    status: "True"
    reason: ReconcileSuccess
    message: "Project reconciled successfully"
    lastTransitionTime: "2025-12-07T15:00:00Z"
  - type: Reconciling
    status: "False"
    reason: ReconcileSuccess
    message: "Reconciliation complete"
    lastTransitionTime: "2025-12-07T15:00:00Z"
  - type: Stalled
    status: "False"
    reason: ReconcileSuccess
    message: ""
    lastTransitionTime: "2025-12-07T15:00:00Z"

Enables status queries via kubectl get <resource> -o jsonpath='{.status.conditions}' and compatibility with kstatus-aware tooling.
