troc: Add Cal.com scheduling integration

[cuevaio]

Summary

This PR adds a Cal.com scheduling integration to the Code Brew website, allowing visitors to easily book meetings with the team.

Changes

• Created a new component that embeds the Cal.com calendar widget
• Added a new "Schedule" section to the main page with the booking interface
• Added a "Schedule" navigation link in the header for easy access
• Configured the Cal.com embed with dark theme to match the site's design system
• Properly typed the Cal.com window API to avoid linting issues

Features

• Responsive Design: The calendar embed adapts to different screen sizes
• Dark Theme: Matches the existing dark aesthetic of the site

• Client-Side Loading: Uses React hooks to dynamically load the Cal.com script

Notes

• The integration is fully client-side and doesn't require server configuration
• Pre-existing build issues in the repository (unrelated to this PR) do not affect the functionality
