feat(api): Entity version filtering

[cvauclair]

Motivation

Allow users to reduce the number of versions returned by the API in cases where only a subset of versions is of interest.

Implementation

Add the following filter object to the GraphQL API

input VersionFilter {
  proposedAt: String
  proposedAt_gt: String
  proposedAt_gte: String
  proposedAt_lt: String
  proposedAt_lte: String
  proposedAt_not: String

  publishedAt: String
  publishedAt_gt: String
  publishedAt_gte: String
  publishedAt_lt: String
  publishedAt_lte: String
  publishedAt_not: String

  author: String
  author_not: String
  author_in: [String!]
  author_not_in: [String!]

  updatedAttributes_contains: [String!]
  updatedAttributes_not_contains: [String!]
}

Note: Many of these filters relate to new entity version fields spec-ed out in

This filter would be used when selecting the versions of an entity, e.g.:

# Schema
type Entity {
  versions(where: VersionFilter): [EntityVersion!]!
}

# Query
query {
  entity(entityId: "Foo", spaceId: "MySpace") {
    # Get versions proposed by Byron since the start of the month
    versions(where: {
      author: "Byron",
      proposedAt_gte: "2025-02-01T00:00:00",
    }) {
      id
      name
    }
  }
}

Note: argument values not accurate
