[INTF25] Build filter for fetch review dashboard query

[ruiichen]

Notion ticket link

Ticket Name

Implementation description

• Added a new type for the filter's possible selections
• Added a new relation to access the position table as well (needed for departments)
• Added a filter factory to create the condition used in the where condition.
• Note: I did not add a filter for selected applicants/conflicts in this PR because the support is not yet there in our database. Adding it once given support is trivial using the current implementation.

Steps to test

1. In PGAdmin4, change the values of the entries in tables such as applicants and applicant_records, and filter for that record in the GraphQL query. Below is the query template.
2. I also tested myself, the tests I have tried are included for your viewing pleasure.

query {
  reviewDashboard(pageNumber: 1, resultsPerPage: 50, filter: null) {
    firstName
    lastName
		position
    timesApplied
    applicationStatus
    choice
    reviewers {
      firstName
      lastName
    }
    totalScore
  }
}

What should reviewers focus on?

• Logic in the where condition is correct

how do you feel if we just pass in a position string instead of making GraphQL guard with an enum. if we can't find anything entries with matching position string, we just return empty array. just looking at this term, we added i think 2 new positions, i think doing it without this enum check would make it easier to add new positions.

do you think we can also do multi-select positions for filtering? i think i see that in the design right now, so it would be good to have that option if it's not too bad to implement 🙏

Looks good to me! But maybe remove the .idea files
