[PM-7169][PM-5267] Remove auth status from account info

[MGibson1]

Type of change

- [ ] Bug fix
- [ ] New feature development
- [x] Tech debt (refactoring, code cleanup, dependency upgrades, etc)
- [ ] Build/deploy pipeline (DevOps)
- [ ] Other

Objective

Adding authentication status to account service has proven to be a mistake. It's better handled as an on-demand check, which is introduced by #8537.

This removes the status from account service entirely, including any current calls to it and set methods.

Before you submit

• Please add unit tests where it makes sense to do so (encouraged but not required)
• If this change requires a documentation update - notify the documentation team
• If this change has particular deployment requirements - notify the DevOps team
• Ensure that all UI additions follow WCAG AA requirements

macOS build had failed, re-ran the job and it passed so it was probably nothing :)

Approving to get stop notifications, just ping me again if my approval gets dismissed during the conflict resolution.

(yes I did spent too much time creating that meme image 🥲)
