Feat: Automatic Setting of Permissions in the Data Directory

[sbaerlocher]

Description

I propose implementing a functionality in dde that automatically checks and sets the permissions in the DATA_DIR or DDE_DATA_DIR before the application starts, using chown based on the environment variables DDE_UID and DDE_GID. This aims to improve user experience and prevent issues with access rights.

Proposed Solution

Implementation of a Bash function to be executed as part of the startup process:

function set_correct_permissions() {
    if [ -d "$DDE_DATA_DIR" ]; then
        echo "Setting correct ownership for the directory $DDE_DATA_DIR to UID: $DDE_UID and GID: $DDE_GID"
        chown -R "$DDE_UID":"$DDE_GID" "$DDE_DATA_DIR"
    else
        echo "Directory $DDE_DATA_DIR does not exist."
    fi
}

Expected Benefit

This adjustment would simplify handling for the user and ensure that permission problems are avoided.

eventually the sudo is needed
