fix(database): table editor focus when the tab opens targets the editor host (#2307) (#2318)

The editor area focuses its own [data-editor-focus] host when a table tab
opens; dbTableEditorFocus only set when focus landed inside
[data-db-table-editor], so Go to Column / Submit / Revert stayed disabled
until a cell was clicked. Treat host focus that wraps a table editor as
table-editor focus too.
