    Use g_return_val_if_fail / g_return_if_fail for NULL guards
    
    Replace verbose if-block NULL checks with idiomatic GLib
    precondition macros, per review feedback.

commit 606fc455820457a7892bc5fda41828a7b7ffa8b7

    Fix segfault in gnc_gsettings_get_settings_obj when GSettings schemas are not installed
    
    Add NULL guards before dereferencing return values from GLib calls to prevent
    segmentation faults when GSettings schemas are missing (e.g., in library-only builds).
    
    The crash occurred when g_settings_schema_source_get_default() returned NULL
    and was passed directly to g_settings_schema_source_lookup(), causing a NULL
    pointer dereference. The existing G_IS_SETTINGS check came too late.
    
    Changes:
    - Add NULL check for schema_source before using it
    - Add NULL check for schema before calling g_settings_new_full()
    - Add NULL guard in gnc_settings_dump_schema_paths() for consistency
    - All callers already handle NULL returns via G_IS_SETTINGS checks
