Added back in existing teams, apps, and admin portal server features

[Charlesthebird]

Summary

This PR resolves the "Existing Features" section of the epic for supporting a GG portal server v1.18 backend.

These are features that existed from the GMG Teams + Apps feature branch. Since the Portal Server API in GG v1.18 is mostly the same as that feature branch, we can re-use and enable the UI code for these features now. These were the original designs for those pages.

Here are demo videos of the different re-enabled features.

Pt 1: API's and API Details pages:

Pt 2: Teams, Team Details, App Details, Apps pages:

Pt 3: Deleting subscription:

Pt 4: Admin features (teams, apps, and subscription management):

Environment Setup

Feel free to go off the videos + code, as the features being added have been mostly reviewed already. Adding in repro steps here though if there is interest.

• Clone the solo-projects repo.
• Run: sh hack/gateway-portal/reproduction/init.sh to partially set up your environment
• Copy the USER_TOKEN=... line that is output around the last lines of the script, and execute that in your terminal.
• Run the following to create the user in the Portal Server DB: curl http://developer.petstore.com:8080/v1/me -X "PUT" -H "Authorization: Bearer $USER_TOKEN"
• Open Keycloak at localhost:8088, log in with username=admin password=admin.
  • Toggle "Confidential" to false on the "Clients" -> "ext-auth-server-client" page.
  • Add "http://localhost:4000/*" under "Valid post logout redirect URIs"
  • Check the "Standard Flow" checkbox
  • Hit "Save"
  • Logout from the keycloak UI.
• In this project, run make run-ui (node version v18.16.0)
• Open localhost:4000, and then log in with username=user1 password=pass

This process will be made easier in the future (noted in the epic issue), so that you will eventually just need to run the solo-projects script and then the UI.

This is being merged into the gg-portal-1.18-features branch, which should work with the portal-server backend in v1.18 of the solo-projects repo.

I forgot what the UX is for this app looks like. Those button after-effects :/

Code changes look fine
