refactor(edgeorder): migrate to unified folder structure (#36171)

* refactor(edgeorder): migrate to unified folder structure

- Consolidate TypeSpec and Swagger files under resource-manager/Microsoft.EdgeOrder/EdgeOrder/
- Move TypeSpec files from EdgeOrder.Management/ to new unified structure
- Relocate all swagger files and examples to service directory
- Update tspconfig.yaml with correct paths and ARM types directory
- Fix all common-types references for new folder depth
- Update readme.md input-file paths for consolidated structure
- Add suppressions.yaml for legacy API versions not yet migrated to TypeSpec
- Ensure TypeSpec compilation works correctly in new structure

This migration aligns with Azure folder structure guidelines where TypeSpec
and swagger files are unified under a single service directory.
