Bug Report — Wrong MONGO_URL and duplicate env vars on default install

[dmxkov]

Chart version: wekan-7.97.0

On a fresh installation using default values, the generated Wekan Deployment includes an invalid MongoDB host in MONGO_URL:

- name: MONGO_URL
  value: mongodb://wekan-mongodb-0.wekan-mongodb:27017/wekan

This hostname (wekan-mongodb-0.wekan-mongodb) does not resolve, because the MongoDB subchart (e.g., groundhog2k/mongodb) creates:

wekan-mongodb            ClusterIP
wekan-mongodb-internal   Headless

so Wekan crashes with MongoNetworkError: getaddrinfo ENOTFOUND wekan-mongodb-0.wekan-mongodb.

Additionally, if env: is not explicitly set to an empty list, the chart renders two MONGO_URL entries (one from the helper and one from defaults), leading to a Helm validation error or nondeterministic environment ordering.

7.97 is old. Instead, please test 7.98 .
