feat: cascade deletes, student notes, import popups, module reorganization

- Cascade delete on all entities (student, module, UE, user, role, promotion)
- Fix Response body reuse bug (factory functions instead of constants)
- Student note viewing via CAS uid (strip non-digit prefix)
- Fix middleware page visibility for students in LOCAL mode
- Import result popup component (shared across all import pages)
- Fix student import to use numEtud from Excel
- Bulk student selection with promo change and delete
- Move UE/UE-Module API and pages from notes to admin module
- Move promotions page from students to admin module
- Multi-year maquette import with per-year promo selection
- Inline promo creation in maquette import
- Static Excel templates (students, notes, maquette)
- Fix XLSX export using blob download instead of writeFile
- Allow students to read modules list (GET /modules)
