fix: cleanup debug prints and wire ENUM/SET dropdown into right sidebar

[datlechin]

Summary

• Remove 16 debug print() statements and an unused logger left over from ENUM/SET dropdown debugging
• Wire ENUM/SET enum values from tab.columnEnumValues into the right sidebar's EditableFieldView so the dropdown picker appears for ENUM/SET columns
• Add metadataVersion to InspectorTrigger so the sidebar reconfigures when Phase 2b loads enum values
• Extend sidebar picker condition to include SET columns (previously only ENUM)

Test plan

• Open a MySQL/MariaDB table with ENUM and SET columns
• Select a row and verify the right sidebar shows dropdown pickers for ENUM/SET fields
• Verify no debug prints appear in console output
• Verify single-click dropdown still works in the data grid for ENUM/SET columns
