[SECONDARY FEATURE] Search-Level Course Category

### User Story
As a student, I want to visually see in the search results whether a course fulfills a GE or major requirement within the search results so that I can easily discern which classes fulfill my educational needs.

### Technical Task:
Insert clear iconography next to a course title within search results to indicate what type of requirement it fulfills.

### Acceptance Criteria:
- Icon appears next to search results if it fulfills a GE or major requirement
- On hover, the icon provides more detail to which GE category or whether it fulfills major-required vs. major elective
- Different icons display for major courses and GE courses. Courses that fulfill both show both icons.
