While I was testing the Sign-out functionality in #46 , I found a bug on login. Sometimes, intermittently, the login wouldn't 'take' even though the login POST was successful and the subsequent GET to `/api/v2/user` was successful - the user would still be brought to the `/login` screen a second time:  ^ I log-in, and then the login screen just resets, and logging in a second time works 🤔 I tracked this down and found it is a new race condition that I inadvertently introduced when I migrated to SWR in #46. Because SWR caches responses based on the API path - we have to invalidate the cache for `/api/v2/user` when the user logins, otherwise we'll continue to serve the user-not-found error until SWR decides to retry. However, we weren't waiting for that cache-invalidation to go through - so there was the chance that an `/api/v2/user` request was still in-flight while we were redirecting after a successful login. If the request made it back prior to the redirect - login would work on the first try. If the request took longer - SWR would serve the stale, erroneous user from the cache. Luckily the fix is simple - `mutate` in the SWR API returns a promise, so we can just wait for that to go through before redirecting. Unfortunately, though, this is tricky to exercise in a unit test because with the SWR model, the login logic is spread between `_app.tsx`, `UserContext.tsx`, and `SignInForm.tsx`, and the race condition involves an integration of all of those places. I found that there is a lint rule that can help protect us from making this mistake - [`typescript-eslint/no-floating-promises`](https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/no-floating-promises.md) (it's a lint rule we wanted to turn on in `coder/m`, too, actually - just a lot of work to clean up the code for it!), so I turned it on as part of this PR, and it caught a couple extra places to check.

Front-End Plan
For the front-end team, we're planning on 2 phases to the 'v2' work:
Phase 1
Phase 1 is the 'new-wine-in-an-old-bottle' approach - we want to preserve the look and feel (UX) of v1, while testing and validating the market fit of our new v2 provisioner model. This means that we'll preserve Material UI and re-use components from v1 (porting them over to the v2 codebase).
Phase 2
Phase 2 is the 'new-wine-in-a-new-bottle' - which we can do once we've successfully packaged the new wine in the old bottle.
In other words, once we've validated that the new strategy fits and is desirable for our customers, we'd like to build a new, v2-native UI (leveraging designers on the team to build a first-class experience around the new provisioner model).
