Refactor storage validation and error codes for containers

Browse Source 
Simplifies and streamlines storage validation logic in create_lxc_container, removing redundant content checks and using direct exit codes for unsupported storage types. Updates error_handler.func with clearer, more specific Proxmox exit code explanations and improves code consistency and readability throughout error handling functions.
