Subject: [PATCH 1/4] fix(schema): use FQCN for modNamespace to resolve PSR-4
 deprecation

Replace class="modNamespace" with class="MODX\Revolution\modNamespace"
in modx.mysql.schema.xml so the profiler and loadClass no longer trigger
the v3.0 deprecation warning for short class name.

Subject: [PATCH 4/4] fix(loadClass): normalize short mod* names to FQCN for
 PSR-4 compatibility

Add isShortModClassName() helper and runtime normalization in loadClass().
Short names (modResource, modAccessContext, etc.) are converted to
MODX\Revolution\* FQCN to avoid deprecation from xPDO call paths.
Creates class_alias for backward compatibility.
