The background validation checks are somewhat convoluted, and misleading with multiple backgrounds, so this PR disables the standard main-background check if FRED is running. It then adds a new FRED-specific background check that covers all backgrounds. Additionally, this PR fixes a bug in an error message in `stars_get_first_valid_background`. Fixes #3116.
