- Updated styles in several components for consistency.
- Added `fetchChainSeo` function for improved SEO handling.
- Replaced `chainMetadata` with `customChainMetadata` in various components.

## Summary by CodeRabbit

- New Features
  - Chain pages now show an interactive FAQ section when SEO data includes FAQs.
  - SEO data is fetched and cached externally to provide richer titles, descriptions, and OpenGraph/Twitter previews.

- Bug Fixes / Behavior
  - Metadata generation now depends on external SEO (may be unavailable), affecting preview availability and link consistency.
  - Chain header images and gas-sponsored indicators now use the updated metadata source.

- Style
  - More compact Supported Products cards, adjusted overview spacing/corner radius, lighter explorer/info-item typography, and refined link styling.
