v1.0.14

feat: MPJ resolve diagnostics + GDB field-name sanitization

- pymapgis.py: _resolve_one() now returns (path, tried_paths) tuple; resolve_layer_paths() stores per-layer diagnostics in self.last_resolve_report with raw_paths/tried_paths/skip_reason fields
- main.py: when an MPJ resolves 0 layers, emit ⚠️ per-layer detail (引用文件未找到 / 重名冲突) to the GUI log instead of silently showing 0
- export_manager.py: add _sanitize_gdb_field_names() that renames unsafe chars (e.g. ID-1 → ID_1) before pyogrio writes, eliminating RuntimeWarning laundering noise; called as step 4b in export_to_gdb()
- version bump v1.0.13 → v1.0.14
