Sort all columns (#3650)

* feat: enhance table column selection and sorting functionality

* fix: update key binding for sorting selected column to Ctrl+O

* remove unused setSelectedColIdx method and sortIndicator function

* test: update expected hints count in various view tests

* test: update expected hints count in TestServiceNew

* fix: update keyboard handling for column selection to use Shift key

* refactor: streamline column selection logic and initialize selected column based on current sort

* fix: change key binding for sorting selected column from Ctrl+O to Shift+S

* test: update expected hints count in help, namespace, pod, and PVC tests
