Containers in nix shell start with different user groups

[l-monninger]

Summary

Upon restarting docker-compose overlays associated with movement-core in the nix shell, a Permission Denied error will prevent reusing the Celestia key files.

This appears to be a product of the nix-shell in nix-shell setup which essentially causes the user passed to Docker Compose to be different upon reopen the shell.

One way around this is to upgrade to the DA Sequencer version of Movement, thereby removing Celestia entirely. This should be first priority.

Important

The FA Sequencer approach requires reconciling the dependency and submodule fixes PR: movement-network/movement#1203

However, this needed to be done at some point.

If the issue persists thereafter, a genuine fix of the user group can be pursued.
