Fix website issues: logo visibility, magazine link, typography, and JS bugs

[Copilot]

Website had several issues: white logo invisible on white background, incorrect magazine URL, outdated fonts, and JavaScript bugs in calendar/community modules.

Changes

Logo Visibility

• Added CSS filter to invert white logo on light backgrounds

.nav-logo img {
    filter: invert(1) brightness(0.3);
}

Magazine Link

• Fixed URL from openrocketsmag.com → mag.openrockets.com

Typography

• Replaced IBM Plex Sans with Space Grotesk for a more distinctive, modern look
• Added Inter as secondary font, JetBrains Mono for monospace

Bug Fixes

• calendar.js: Fixed hardcoded Dec 2024 dates → relative dates using getDateOffset()
• community.js: Fixed syntax error with duplicate closing braces breaking the CommunityManager class

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• thebulleteen.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)
• thehatclub.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
