Clean up dead code and unused assets

- Remove trust-indicators JavaScript animations from animations-enhanced.js
- Clean up translation keys for removed indicator elements
- Remove selector references from config.js
- Fix missing video reference (hero-tech-pattern.mp4)
- Remove massive unused CSS sections: timeline, digital-beat, neural network viz
- Reduce animations.css from 2669 to 272 lines (90% size reduction)

This removes code that was referencing non-existent HTML elements
and large unused visual effects from previous design iterations.
