Buf renames Custom plan to Enterprise, drops Kafka integration access

Top-tier 'Custom' plan renamed to 'Enterprise' across the pricing card, tab selector, and comparison table header; pricing and feature set unchanged. Kafka integration removed from the top-tier plan: the 'Access to the BSR's Kafka integration' bullet and the 'Kafka Integration' comparison table row are both gone.
