📄 Description

This commit implements the remaining 5 of 8 grid lines:
left/top/right/bottom (COMMON_LVB) borders and double underline

AtlasEngine::_resolveFontMetrics was partially refactored to use floats
instead of doubles, because that's what the remaining code uses as well.
It also helps the new, slightly more complex double underline calculation.

Validation Steps Performed

  • Print characters with the COMMON_LVB_GRID_HORIZONTAL, GRID_LVERTICAL,
    GRID_RVERTICAL and UNDERSCORE attributes via WriteConsoleOutputW
  • All 4 grid lines are visible ✅
  • Grid lines correctly scale according to the lineWidth ✅
  • Print a double underline with printf "\033[21mtest\033[0m"
  • A double underline is fully visible ✅
