feat(orgAdmins): show total user & team counts

[tianrunhe]

Description

Fixes #10393

Demo

Testing scenarios

[Please list all the testing scenarios a reviewer has to check before approving the PR]

• Organizations page show total user count

  • Go to http://localhost:3000/me/organizations
  • See total number of users displayed

• Enterprise plan show total number of teams and users

  • Go to the billing page for an enterprise org: http://localhost:3000/me/organizations/xxxxx/billing
  • See total number of teams and users displayed above of plans

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

-1 we're removing active for all users here. It's still relevant for Team users, so I think it should only be hidden for Enterprise users

+1 the plans section doesn't feel like the right place for this, to me. The plans explain what is offered in each tier, whereas this is information about usage.

I'm happy to still approve the PR if that's where you and @charlesmathias what to put it, but I'd suggest checking with @ackernaut first

Sooner or later I’d like to create a usage section that is separate from the tiers and plans setion(s). Kind of like variants we’ve explored here 🔒 . It doesn’t have to happen in this PR.

I would like to see the usage section always at the top, regardless of how the other sections appear or are ordered below. If we need to add some special case banner to alert something at the very top, probably something that can be dismissed, we can always consider that later.
