feat: add community-connections API endpoint and update profile handler

New PATCH /api/members/me/community-connections endpoint following peer-support.patch.js pattern (requireAuth, validateBody, dot-notation $set, Slack user lookup when offerPeerSupport+slackHandle set, logActivity).

Profile endpoint updated with craftTags handling, craftTagsPrivacy and communityConnectionsPrivacy in privacy fields, and craftTags in response.
