core, ui: auto-accept group invitations per user profile (#7377)

* core, ui: auto-accept group invitations per user profile

Add a per-profile toggle for auto-accepting group invitations, and regroup it
with the existing contact-requests setting under a single Auto-accept section
in Privacy & Security, relabelled "Contact requests in groups".

The join is fully async. processGroupInvitation already had an async accept
path, used when the invitation matches a group link the user opened:
prepareAgentJoin + createMemberConnectionAsync + joinAgentConnectionAsync,
with the outcome reported later against the CFJoinConn command id. Auto-accept
takes that same path instead of going through APIJoinGroup, so it works while
the app is closed and never blocks message processing.

An auto-accepted invitation still records a CIRcvGroupInvitation item in the
chat with the inviting contact, so there is a record of who added the user to
which group.

Two details worth noting for review:

hostContact is reported to clients only for group links. Clients respond to it
by replacing the transient host connection view with the group and removing
that chat - correct for a group link, where the contact is a placeholder, but
wrong for a plain invitation, where it is a real contact.

A resent invitation returns the existing group, because createGroupInvitation
is idempotent on inv_queue_info. The join therefore only runs while the
membership is still GSMemInvited, so a resend cannot open a second connection.
