fix: revert shared styles, use standalone styles per block

- Reverted shared SCSS approach that may have caused CSS variable issues
- Each block now has complete standalone styles
- category-integrations copies integration-feature styles with scoping
- Direct values instead of CSS variable indirection for reliability
