feat(site): overhaul domain and monitor detail views

Refactor the domain and monitor detail pages to use a new modular
component architecture. This includes:

- Implementing `domain-info-sections.tsx` and `monitor-info-sections.tsx`
  to provide structured, card-based information layouts.
- Enhancing domain details with new sections for DNS, SSL, SEO, and
  hosting information.
- Improving monitor details with enhanced uptime visualizations and
  response time statistics.
- Updating the PageSpeed check API to support an optional API key from
  environment variables.
- Cleaning up UI components and improving code formatting in the
  monitors table.
- Updating localization files to support new UI strings.
