Professional connections and GigxMatch past shows

New professional network tools

Verified artists and venue managers can send, accept, decline, cancel, and remove mutual Connect relationships.
Public profiles can show privacy-respecting mutual connections.
Account Settings now controls Connect invitations and public mutual-connection previews.

Completed GigxMatch Shows appear under Past shows (GigxMatch verified) for accepted lineup artists and linked venues.
Each owner chooses Public or Not public for their own profile only. Multi-party agreement is not required.
When a Show completes, related users receive a short email and in-app notice to set visibility and invite collaborators again.
Artists can open the management page from the pen icon on their public profile.
Admin can set a Show to Hidden, which removes it from the Past shows list and from public profiles.

On Connections, accepted connections show role-based shortcuts such as Invite to show or Gig request.
A periodic Connect digest reminds eligible users to collaborate again (at most once every 14 days).

GigxMatch adds mutual Connect relationships, shared-network previews, and completed-show profile visibility.
