visual hierarchy, hover states, and stats in footer

- Table view: unified flat table with clickable column headers for sorting
(Type, Titre, Créateur, Participant, Stats, Date)
- Add Créateur column showing the workshop owner with Gravatar avatar
- Widen Type column to 160px for better readability
- Improve tabs navigation with pill-shaped active state and shadow
