refactor(styles): move component-specific CSS into Astro components

- relocate header, footer, nav, hero, and page-hero styles into their owning components
- move blog index, blog post, team, video, insurance, CTA, and home-section styles out of the global sheet
- keep  focused on shared primitives such as buttons, cards, links, and list styling
- preserve existing layout and responsive behavior while reducing global CSS scope
