Fix: failing p3 test for SDK/HTTP APIs (#13062)

### What problem does this PR solve?

Adjust highlight parsing, add row-count SQL override, tweak retrieval
thresholding, and update tests with engine-aware skips/utilities.

### Type of change

- [x] Bug Fix (non-breaking change which fixes an issue)
