Implement bulk export/push with resource list

- Add Resources field to ExportJobOptions to support exporting specific resources
- Implement ExportSpecificResources function that:
  - Validates resources (rejects folders, managed resources, unsupported types)
  - Loads unmanaged folder tree to replicate folder structure
  - Supports dashboard version conversion using shared shim logic
  - Replicates folder structure by concatenating Path + folder path from unmanaged tree
- Update ExportWorker to dispatch to ExportSpecificResources when Resources list is provided
- Add validation in validator.go for ExportJobOptions Resources field
- Add comprehensive unit tests covering all scenarios
- Update WriteResourceFileFromObject to handle folder path resolution
