Use pragmas setting in Table Preview queries #2574
Description
Summary
As a follow-up to PR #2563, the "Pragmas" setting from the Query Settings Dialog should also be applied to all preview queries in the Table Preview feature. Preview queries should include the pragmas at the beginning, just like regular query executions.
Acceptance Criteria
- Whenever a Table Preview query is run, the value of the current "Pragmas" setting is prepended to the SQL.
- This works for all tenant/table previews where the Query Settings Dialog is in use.
- Tests are updated to cover this logic.
- Documentation and i18n are updated if necessary.
Context
- Related PR: feat(query): add multi-line Pragmas field to Query Settings Dialog #2563
- Motivation: Consistent application of pragmas for all query executions, including previews.
