Improve docs UI and Mermaid rendering (#125)

Refactor documentation for clarity and organization. Upgrade the
@biomejs/biome dependency to version 2.4.9. Clean up imports and improve
component structure in the documentation pages.

## Summary by Sourcery

Refine documentation rendering and UI components while updating tooling
dependencies.

New Features:
- Improve Mermaid diagram rendering in docs with explicit SVG rendering
and stricter security configuration.

Bug Fixes:
- Use stable keys for mapped feature and FAQ items on the docs home page
to avoid React key issues.
- Adjust field error list keys to avoid collisions and improve React
reconciliation.

Enhancements:
- Clean up and reorder exports, imports, and hook dependencies across UI
components for consistency and maintainability.
- Streamline docs routing and loader types by removing unused parameters
and simplifying language handling.
- Improve user-facing error and status messages with template literals
and clearer formatting.

Build:
- Upgrade @biomejs/biome to version 2.4.9 and consolidate Biome
configuration by removing redundant docs-specific settings.

Documentation:
- Tidy documentation page composition and table-of-contents handling for
clearer structure.
