Previously we were relying on a snapshot-based check to detect invalid execution contexts. However, when WAIT FOR is wrapped into a stored procedure or a DO block, it could pass this check, causing an error elsewhere. This commit implements an explicit isTopLevel check to reject WAIT FOR when called from within a function, procedure, or DO block. The isTopLevel check catches these cases early with a clear error message, matching the pattern used by other utility commands like VACUUM and REINDEX. The snapshot check is retained for the remaining case: top-level execution within a transaction block using an isolation level higher than READ COMMITTED. Also adds tests for WAIT FOR LSN wrapped in a procedure and DO block, complementing the existing test that uses a function wrapper. Relevant documentation paragraph is also added.
