feat: Add responsive mobile navigation with Discord-style sidebar layout (#138)

Implements a mobile-first navigation reorganization that moves controls into the sidebar at smaller breakpoints:

- Community button moves to sidebar at 600px
- Projects dropdown moves to sidebar at 480px
- Sidebar gains proper width constraints (100% width, 400px max-width)
- Full-height layout styling fixes for proper flex behavior
- Clean separation between header and sidebar responsibilities

This creates a Discord-like mobile experience where the sidebar becomes the primary navigation container on smaller screens.
