Github OAuth App Error - CR DB expects "last_name" field

Hi all,

Having some issues with the Github Integration. I cleared my entire setup to try again from scratch, beginning with the Github OAuth setup.

Reproduction steps:

Start with a clean setup, clone the huly-selfhost repo, and run `./install.sh`. Using caddy as a reverse-proxy in front of the nginx container but shouldn't make a difference here.

I created a personal OAUTH app in github, and added the two environment variables (`GITHUB_CLIENT_ID` and `GITHUB_CLIENT_SECRET`) to the `account` service. I left the ACCOUNTS_URL in the front container unchanged since it seemed correct.

However, when I try logging in, I get this issue:

```

Which, my LLM analyzed and saw that there was an unfulfilled requirement for "last_name" coming from the DB.

**Workaround:**

Signing into the database using:

`docker exec -it huly_v7-cockroach-1 ./cockroach sql --insecure --user=selfhost`

and entering the DB password (found in .env file).

Then, run:

```
selfhost@localhost:26257/defaultdb> ALTER TABLE global_account.person ALTER COLUMN last_name DROP NOT NULL;
ALTER TABLE
```

This effectively drops the requirement for a "Last Name". I'm now able to log in with Github.
