fix: add pm-integration-features-group classes for theme compatibility

Category integrations block now uses pm-integration-features-group class
so site theme styles (like .integration-content .pm-integration-features-group)
apply correctly for borders, backgrounds, and other styling.

Changes:
- Added pm-integration-features-group and has-features classes to wrapper
- Added pm-integration-features-group__header class to header
- Added pm-integration-features-group__features class to features container
