* feat: add template rollback endpoint [LET-7423]
Adds POST /v1/templates/:template_name/rollback endpoint to restore templates to previous versions.
Key features:
- Rollback to any numbered version (1, 2, 3, etc.) or "latest"
- Auto-saves unsaved changes before rollback to prevent data loss
- Validates input (rejects "current"/"dev" as target versions)
- Preserves entity IDs and relationships across rollback
- Uses project context from X-Project header (no project_id in path)
Implementation includes:
- API contract in templatesContract.ts
- Handler in templatesRouter.ts with comprehensive error handling
- 9 E2E tests covering functionality and edge cases
- Updated stainless.yml for SDK generation

* chore test
* fix: add X-Project header to rollback endpoint tests
The rollback endpoint uses project context from X-Project header instead of URL path.
Updated all rollback test calls to include the X-Project header with testProject value.
This follows the no-project-in-path pattern for template endpoints.

* feat: support both URL patterns for rollback endpoint
Added dual URL pattern support for rollback endpoint:
- `/v1/templates/:project_id/:template_name/rollback` (with project in path)
- `/v1/templates/:template_name/rollback` (NoProject, uses X-Project header)
Backend supports both patterns, but Stainless only exposes the cleaner NoProject version for SDKs.
Key changes:
- Fixed "rollback to latest" bug by resolving target version BEFORE auto-saving
- NoProject route is exported first to ensure correct route matching order
- Updated tests to use project_id in path for better compatibility
- All 8 rollback tests passing
