 * One-time migration: rename ecology fields to board across members and activity logs.

 * Renames on Member documents:
 *   communityEcology           → board
 *   privacy.communityEcology   → privacy.board
 *   onboarding.ecologyPageVisited → onboarding.boardPageVisited
 *
 * Renames on ActivityLog documents:
 *   action: 'community_ecology_updated' → action: 'board_updated'
