feat(election): Board of Directors module — appoint, manage, and track elected directors

- New director-board component: 2-step drawer (pick WON candidate → fill appointment details)
- Pending appointments section: highlights WON candidates not yet given a designation
- mat-datepicker for all date fields; tenure end auto-fills to +5 years from start
- Frontend validation: required field indicators + inline mat-error on submit attempt
- Past dates disabled via [min]="today" on all date pickers
- mat-select for Designation and Status (CBS outline style)
- Election service: appointDirector, updateDirector, deleteDirector, getDirectors, getPendingDirectors
- Route added: /election/directors; nav link in election dashboard
- Error handler: suppress 404 toast for /election/directors (backend not yet deployed guard)
