Polish UX: auto-redirect on create, fix design consistency

- createModule now redirects to module page after creation
- createLesson now redirects to lesson editor after creation
- Regenerate Prisma client to fix missing types (category, accessLog, expiresAt)
- Rewrite sortable-modules/lessons with Second Brain design tokens (remove amber/slate)
- Rewrite lesson-editor toolbar and toggle with design tokens
- Fix register page/form: replace amber theme with card-aubade design
