Ghazi-raad f704001eb7 Merge pull request #28120 from Ghazi-raad:test/line-connectivity-26413
Test: Add regression test for LINE_4 vs LINE_8 connectivity #28120 

Add test to verify correct behavior of LINE_4 (4-connected) and LINE_8 (8-connected) line drawing. This test ensures:

- LINE_4 produces staircase pattern (more pixels) for diagonal lines
- LINE_8 produces diagonal steps (fewer pixels)
- LINE_4 pixels have only horizontal/vertical neighbors (no diagonal-only)

Regression test for issue #26413 where LINE_4 and LINE_8 behaviors were swapped.
