Backup and Restore improvements

• Backup and Restore are clearly separated into two dedicated sections using tab navigation

• On single-node clusters with additional storage, only core applications are selectable during Cluster restore (Disaster Recovery)

• After Cluster restore, users are guided to the Restore page to continue restoring applications when available

• Restore actions are clearly visible and enabled only when applicable

• The Backup page now clearly highlights primary actions and main sections, surfacing key information that was previously hidden behind tooltips

• Backup destinations management is clearer and more explicit:
  the section has been renamed to Backup destinations
  destinations can be imported directly from an existing cluster backup file

• Manual backup execution now provides immediate user control with Cancel backup action available directly on the running task

Overall, these changes reduce ambiguity, improve recoverability under stress, and make backup and restore workflows more predictable and safer for administrators.
