feat(metrics): add mutation to generate usage report

[tianrunhe]

Description

Fixes #10001

The spec did mention another argument orgId to filter with a particular org but I don't want to get too complicated in the first version, especially considering in a month this query has to be re-written when we fully migrated MeetingMember and NewMeeting table to PG.

Demo

Testing scenarios

mutation {
  runOrgActivityReport(
    startDate: "2024-01-01T00:00:00.000Z") {
    ... on RunOrgActivityReportSuccess {
      rows {
        monthStart
        signupCount
        participantCount
        meetingCount
      }
    }
    ... on ErrorPayload {
      error {
        message
      }
    }
  }
}

Final checklist

• I checked the code review guidelines
• I have added Metrics Representative as reviewer(s) if my PR invovles metrics/data/analytics related changes
• I have performed a self-review of my code, the same way I'd do it for any other team member
• I have tested all cases I listed in the testing scenarios and I haven't found any issues or regressions
• Whenever I took a non-obvious choice I added a comment explaining why I did it this way
• I added the label Skip Maintainer Review Indicating the PR only requires reviewer review and can be merged right after it's approved if the PR introduces only minor changes, does not contain any architectural changes or does not introduce any new patterns and I think one review is sufficient'
• PR title is human readable and could be used in changelog

I get some strange results with the month end date

      {
          "monthStart": "2024-03-01T00:00:00.000Z",
          "lastDayOfMonth": "2024-03-30T23:00:00.000Z",
          "orgName": "All Organizations",
          "signupCount": 0,
          "loginCount": 0,
          "participantCount": 0,
          "meetingCount": 0
        },
        {
          "monthStart": "2024-04-01T00:00:00.000Z",
          "lastDayOfMonth": "2024-04-29T22:00:00.000Z",
          "orgName": "All Organizations",
          "signupCount": 0,
          "loginCount": 0,
          "participantCount": 0,
          "meetingCount": 0
        },

Note the time.

Also if I query for endDate: "2024-09-16T00:00:00.000Z" I get the result as

 {
          "monthStart": "2024-09-01T00:00:00.000Z",
          "lastDayOfMonth": "2024-09-29T22:00:00.000Z",

which is misleading, because we only count till the end date. I propose removing the lastDayOfMonth field.

I updated the code to remove the loginCount following this comment from Jordan. @Dschoordsch can you take another look? Thank you!

p.s. Also updated the screenshot & test GraphQL query
