fix : resolve runtime errors and improve configuration

- Add explicit imports for useClientService/useProjectService (not auto-imported from services/)
- Fix AppDrawer v-if placement on Teleport to avoid slot warning
- Add json format support in API Platform config (415 fix)
- Support both hydra:member and member keys in extractHydraMembers
- Add Vite/Nitro dev proxy for API calls
- Update CLAUDE.md with full project documentation
- Use tertiary-500 background for project cards
