Implement comprehensive status condition management

[Shahab96]

The operator needs comprehensive status condition management to provide clear visibility into the reconciliation state of Tenant resources. This includes standard Kubernetes conditions like Ready, Progressing, and Degraded.

Current Behavior

• Basic status updates exist but lack comprehensive condition management
• TODO comment at src/reconcile.rs:92: "Implement comprehensive status condition updates on errors (Ready, Progressing, Degraded)"
• Limited visibility into reconciliation progress and errors

Desired Behavior

Implement standard Kubernetes status conditions:

• Ready: Tenant is fully reconciled and operational
• Progressing: Tenant is being reconciled (creating/updating resources)
• Degraded: Tenant has errors or issues that need attention

Each condition should include:

• Status (True/False/Unknown)
• Reason (machine-readable identifier)
• Message (human-readable description)
• LastTransitionTime

Implementation Considerations

• Add Conditions field to TenantStatus
• Update conditions throughout reconciliation loop
• Set appropriate conditions on errors via error_policy()
• Add helper functions for condition management
• Update examples and documentation

Priority

High - Core Stability (from ROADMAP.md)
