Add ComfyUI workflow template links

Adds a **Workflows** section to the model card so the templates that work with these files can be opened or downloaded straight from the repo page.

- 7 templates from [Comfy-Org/workflow_templates](https://github.com/Comfy-Org/workflow_templates), all first-party (no community `templates_*` submissions) and all runnable with stock ComfyUI nodes.
- Attribution follows the template library's own `models` metadata: a template is listed here only when the model it belongs to is the one hosted in this repo. Templates that merely borrow this repo's files are left out.
- Each row shows the template's preview at a uniform 200 px, laid out side by side under a fixed two-column grid so single- and dual-preview templates line up. Dual-preview templates show their before/after pair, labelled, in the order before → after.
- Audio templates show their official audio preview player instead of a thumbnail.
- Ordered by template usage, most used first.

Nothing else in the README is changed.
