Enhance UI components and improve user layout

[QwertyMD]

Type Safety and Data Handling Improvements:

• Refactored ProjectSection to use TypeScript types for state and props, improving type safety and maintainability. Also updated the project filtering logic to handle both string and object tag types. [1] [2] [3] [4]

UI and Visual Enhancements:

• Replaced emoji icons in project filters with Lucide icons for a more consistent and professional appearance.
• Updated the project card layout for better visual hierarchy, including moving images to an overlapping, prominent position and refining card shadows and spacing.

Section and Layout Consistency:

• Added a styled heading and wrapper to the FAQ section for improved section separation and clarity. [1] [2]
• Updated the "Team" and "What's Happening" section headings for consistent capitalization and removed unnecessary padding and descriptive text for a cleaner look. [1] [2]

Homepage and Navigation Adjustments:

• Adjusted rocket image positions and sizing on the homepage hero section for better visual balance, and increased vertical spacing in the hero panel for improved layout. [1] [2] [3]
• Changed the user navigation bar from sticky to fixed positioning for improved persistent visibility during scrolling.

Other Minor Tweaks:

• Commented out the dynamic opacity calculation in .hero-motion-panel to possibly address a visual bug or to test a different effect.
