feat(studio): improve context compression UI and provider display

- Add visual indicator when messages are collapsed (folder icon)
- Add animation to token bar during compression (pulse effect)
- Token bar becomes more compact after compression with "· compressé" label
- Button "voir plus" to expand collapsed messages
- Add 24px spacing at end of feed to avoid last message clipping
- Simplify provider display: show name only, badge "active" instead of key status
- Dashboard: show provider name only without model suffix
- Studio /model: show just provider name, not model
- Z.AI (GLM): mark as crush-only, no external quota check
- Claude: check /usr/bin/claude installation instead of API
