test(ui): pin hunk-centering test expectations to literals

Follow-up to #83. The WrapMode, WithAnnotation, and CollapsedMode tests
computed expected offsets via the same helpers (wrappedLineCount,
wrappedAnnotationLineCount, cursorViewportY) that centerHunkInViewport
uses internally, so a bug in any helper would fail both sides of the
assertion and hide regressions.

Replace helper calls with literal constants derived from test setup:
- WrapMode: force singleFile mode for deterministic wrap width (73),
  200 'a' chars wrap to 3 rows, hunk height = 1 + 3 = 4
- WithAnnotation: short annotation contributes 1 row, hunk height = 3
- CollapsedMode: 3 hidden removes contribute 0 rows, hunk height = 3

Also add a comment to centerHunkInViewport explaining that the hunk-end
scan intentionally includes hidden ChangeRemove lines because
hunkLineHeight returns 0 for them.
