Fix contest ranking table styling for dark mode

[boomzero]

Purpose

Fix broken styling on contest ranking pages (contestrank-oi.php and contestrank-correct.php) where XMOJ server inline styles caused white/light backgrounds and unreadable text in dark mode.

Implementation

Changelog

• Header row: Force black background with white text on all header cells (including problem letter <a> links), removing bgcolor attributes and using !important to prevent Bootstrap overrides
• Data rows (cells 0-4): Clear inline backgroundColor and color from the XMOJ server so Bootstrap's dark theme applies correctly
• Data rows (row element): Clear inline backgroundColor on <tr> elements
• OI ranking solved cells: Fix rgb() → rgba() for background with alpha channel
• Correct ranking score cells: Add missing style.color for dark mode text visibility
