fix(azure-data-explorer): keep the Show Operations and Show Table Details cards from painting empty

check:canvas-sentences flagged the Show Operations sentence: it anchored
`core` on operationId, which is an advanced-mode optional field, so an
untouched card resolved to nothing and painted empty. Show Table Details
had the same shape in milder form — table is optional there, since
omitting it describes every table, leaving a dangling preposition.

Both now lead with literal copy and treat their field as an optional
refinement. Also simplifies the primary-table condition to a single
`!= null` check.
