Subject: [PATCH] fix(mudcraft): fix LuckPerms init by removing subPath mounts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SubPath mounts into plugin directories were causing k8s to create those
directories owned by root before the server process could write to them.
LuckPerms was failing with "Unable to create libs directory" as a result.

Move config injection to the initContainer: it now cleans stale JARs
(rm *.jar), copies fresh JARs from the plugins image, and pre-creates
the LuckPerms and PurpurExtras directories with configs copied from
ConfigMaps. Main container no longer mounts configs via subPath.

Also fixes stale JAR accumulation — initContainer now clears old JARs
before copying, preventing broken old versions from loading.
