Fix automated database restore pod name and add wait for pods

Fix two critical issues in automated database restore:

1. Wrong pod name construction:
   - Before: Used backup name (openstack) → openstack-restore-openstack
   - After: Use restore CR name (openstackrestore) → openstack-restore-openstackrestore
   - GaleraRestore CR naming: <backupName>restore

2. Missing wait for pods to be ready:
   - GaleraRestore CRs were created but pods not ready yet
   - Added wait task that:
     - Waits up to 5 minutes for pod to be created
     - Waits for pod Ready condition (timeout 5 minutes)
     - Ensures pods are running before attempting restore

Changes:
- Add BACKUP_NAME and RESTORE_NAME variables for clarity
- Construct pod name using RESTORE_NAME (not BACKUP_NAME)
- Add wait task after creating GaleraRestore CRs
- Wait for each pod individually before proceeding to restore

Example:
  Backup name: "openstack"
  Restore CR name: "openstackrestore"
  Pod name: "openstack-restore-openstackrestore"

This fixes the "Restore pod not found" error in automated mode.
