Add Phase 8: lesson plan templates with deep-copy instantiation
- New tables: lesson_plan_template, lesson_plan_template_section, lesson_plan_template_item - skill_level enum: beginner, intermediate, advanced, all_levels - Templates are reusable curriculum definitions independent of any member/enrollment - POST /lesson-plan-templates/:id/create-plan deep-copies the template into a member plan - Instantiation uses template name as default plan title, accepts custom title override - Instantiation deactivates any existing active plan on the enrollment (one-active rule) - Plan items are independent copies — renaming the template does not affect existing plans - 11 new integration tests
