refactor(board): delete old board routes, absorb slackHandle into profile PATCH

- Delete server/api/members/me/board.patch.js and server/api/board/suggestions.get.js
- Add boardSlackHandle to memberProfileUpdateSchema; remove boardPrivacy
- profile.patch.js: write boardSlackHandle -> board.slackHandle; drop boardPrivacy
- Remove privacy.board field from Member model
- onboarding/status.get.js: hasProfileTags now requires only craftTags; hasEngagedBoard uses BoardPost.exists
- onboarding/track.post.js: graduation check uses BoardPost.exists instead of board.topics elemMatch
- members/[id].get.js and directory.get.js: reduce board response to slackHandle only; drop connectionTag and peerSupport filters
