Mark Gregory 819e5cf46e Changes
* Replaced the nested export form with a scrollable layout.
* Made the table selection checkboxes directly visible.
* Preserved the Select All and Select None buttons.
* Kept the view selection controls.
* Cleared stale table selections when switching databases.
* Added automatic database loading when the application opens.
* Preserved the existing SQL editor and administration functionality.
