feat: New Template Library (#7062)

## Summary

Implement the new design for template library

## Changes

- What
  - New sort option: `Popular` and  `Recommended`
  - New category: `Popular`, leverage the `Popular` sorting
  - Support add category stick to top of the side bar 
- Support template customized visible in different platform by
`includeOnDistributions` field

### How to make `Popular` and `Recommended` work

Add usage-based ordering to workflow templates with position bias
correction, manual ranking (searchRank), and freshness boost.

New sort modes:
- "Recommended" (default): usage × 0.5 + searchRank × 0.3 + freshness ×
0.2
- "Popular": usage × 0.9 + freshness × 0.1

## Screenshots (if applicable)
