perf: implement multi-phase performance optimizations for PageSpeed 90+

- Resized and compressed oversized logo (204KB -> 21KB)
- Optimized large media images (hs-kabel.png, contact-hero.jpg)
- Implemented dynamic lazy-loading for home page sections
- Tuned Sentry traces sample rate (1.0 -> 0.1)
- Refined font loading and fixed redundant analytics tracking
