feat: add popover with link to Wan Fun Control template on pricing table (#7363)

## Summary
- Add clickable popover to the "What is this?" help text in video
estimates
- Explains that estimates are based on the Wan Fun Control template for
5-second videos
- Includes direct link to try the template:
`cloud.comfy.org/?template=video_wan2_2_14B_fun_camera`

This improves user understanding of how video estimates are calculated
and provides easy access to try the template that the estimates are
based on.
