Subject: [PATCH 1/2] feat(connections): hide schema edit button for non-SQL
 databases

The Edit schema button on the connection card now only appears for
SQL databases (Postgres, MySQL, Oracle, MSSQL, IBM DB2, ClickHouse),
since the Schema Assistant can only generate DDL for those engines.

Subject: [PATCH 2/2] fix(schema-viewer): stop wheel propagation on tables
 sidebar

Wheel events over the tables list bubbled to the viewport's zoom
handler, so scrolling the list zoomed the diagram instead of scrolling.
