chore: rename LCRE branding to LCE-Revelations

Renames release artifacts, Docker image, container/service names,
and shell wrappers from the legacy LCRE prefix to LCE-Revelations.

* Banner asset: LCRE-banner.png to LCE-Revelations-banner.png
* Docker compose service and container: minecraft-lce-dedicated-server
  to lce-revelations-dedicated-server
* ghcr image: ghcr.io/itsrevela/minecraft-lce-dedicated-server to
  ghcr.io/lce-hub/lce-revelations-dedicated-server
* Dockerfile MC_RUNTIME_DIR default points at the CMake build output
  path now that the legacy x64/ MSBuild path is no longer produced
* README and helper shell scripts updated to match

Workflow rename for nightly.yml release notes is folded into the
FourKit commit because the FourKit CI changes overwhelm the diff.
