feat: add EditAsignaturaButton and EditBibliografiaButton components for managing asignaturas

- Introduced EditAsignaturaButton for editing asignatura details with a dialog interface.
- Added EditBibliografiaButton for managing bibliographic references with various utility actions (trim, dedupe, sort, import, export).
- Created reusable Field, Section, and Stat components for better UI structure.
- Implemented typeStyle utility for styling based on asignatura type.
- Integrated new components into the existing asignatura route.
- Updated package.json to include new dependencies for alert dialogs and tooltips.
- Defined Asignatura type in a new types file for better type safety.
