refactor: rename Materia to Asignatura across the codebase

- Updated type definitions and interfaces to replace 'Materia' with 'Asignatura'.
- Refactored components and routes to reflect the new naming convention.
- Adjusted related types and constants for consistency.
- Removed the old Materia type definition and added Asignatura type definition.
- Ensured all references in UI components and logic are updated accordingly.
