fix(M01): correct ADT filename coordinate axes

Browse Source 
Work-Package: M01-FND-COORD-TILE-AXIS-002
Agent: sindo-main-codex
Tests: coordinate mapper, M00 calibration, baseline manifest, coordination and documentation gates passed
Fidelity: Azeroth_31_49 raw MCNK origins and OpenRealm confirm filename X from world Y and filename Y from world X

## Known gaps and risks
- Existing native loaders and renderer scripts still contain manual conversions.
- Current `StreamingWorldLoader` tile names may represent Godot X/Z ordering rather
than ADT filename X/Y; migration must preserve visible baseline behavior.
- Contract version 1 briefly transposed ADT filename/chunk axes; version 2 fixes
the defect before any consumer migration.
- MDDF/MODF rotation comments and implementations disagree across existing paths;
this package deliberately does not generalize them into world yaw.
- Finite-number validation belongs to external format adapters and is not yet implemented.
