fix(billing): align Pro seat limit to 10, remove per-seat remnants

Per-seat pricing was removed in e706bcb but Pro team.members limit
stayed at 25 while seats_included was 10. With flat-rate billing
these must match — Pro now consistently allows 10 seats.

Also includes: REST API feature removal from ee/ scope, webhook
event emissions for merge/reject/content/model endpoints, and
windsurfrules SEO example update.
