fix(tables): restore the workspace ownership check on copilot row deletes

Switching deleteRow/deleteRowsByIds to take a TableDefinition dropped the
workspaceId argument that previously scoped the query, and the two branches
I added loaded the table without the ownership comparison every other
operation in the tool performs — letting a caller delete rows from a table
in another workspace. Both now reject a foreign table as not found.
