Subject: [PATCH] fix(docker): add PARTY_ROLE environment variable for
 server-party-api
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add PARTY_ROLE=delegate environment variable to server-party-api service
to fix nil pointer dereference when determining party role during keygen.

Without this variable, the party defaults to "persistent" role which tries
to access keyShareRepo (nil for delegate parties), causing a panic.
