Wrap members directory page in PageShell. Also expand visual mask
selectors to cover .filter-bar, .skills-bar, and .connections-section
because filter content varies based on dynamic tag/topic state and
async fetch ordering. Rebaselines several existing snapshots that now
mask wider regions but capture the same structural layout.
Update member directory and public profile APIs to include craftTags
and communityConnections with privacy-aware filtering. Directory now
uses predefined tags from the Tag model for filter bars and supports
craftTag/connectionTag query filters. Frontend shows craft tag pills
and cooperative topics with state labels, falling back to old
offering/lookingFor fields. Add Connections nav item.
