BetterKnightsUI 2.0

New: Copy for AI
Every course now has a "Copy for AI" button in its title bar. One click
copies that course's full section table as markdown — status, section,
mode, days and times, room, meeting dates, plus each instructor's
RateMyProfessors score and profile link. Paste it straight into ChatGPT
or Claude to compare sections or plan a schedule.

Fixes
• Restored Bootstrap and Font Awesome styling — buttons, fonts, and
icons render correctly again instead of showing empty boxes.
• Darkened the mid-range rating badge so the number is readable.
• Professors named Bonnie now show their ratings instead of appearing
unrated.
