Subject: [PATCH] fix(proxy): serialize team budget_limits to JSON in
 jsonify_team_object

POST /team/new with any budget_limits returned 500 because
jsonify_team_object serialized members_with_roles but left budget_limits
as a raw Python list, which Prisma's Json column rejects. /team/update
and /key/generate worked only because each json.dumps the windows itself.
Serialize budget_limits in the shared helper, guarded by isinstance(list)
so the pre-serialized /team/update path is unaffected.
