Task #375: Changed row coloring behavior in the HTML-table PDF renderer
so that normal rows only color the # (number) and الاجتماع (meeting)
cells, leaving الحضور (attendees) and الوقت (time) cells white.
When a row has merged columns (colspan), the entire row is colored
as before.
Implementation: `buildMeetingRow` now assigns `bgStyle` directly to
the first two cells' `style` field. `renderCells` takes an `allColored`
flag — true for merged rows (applies bgStyle to all cells), false for
normal rows (uses each cell's own style). The `<tr>` element no longer
carries the background style.
File changed: artifacts/api-server/src/lib/pdf-html-renderer.ts
