Closes coder/internal#1622 (ENG-3061).
## Problem
`main` is broken: the chatd test package fails to compile, taking down
`lint`, `test-go-pg`, `test-go-pg-17`, and `test-go-race-pg`.
This was a semantic merge conflict between two individually green PRs:
- #27170 removed `APIKeyID` from `chatd.CreateOptions` (chatd now mints
a synthetic gateway key from the chat owner).
- #27070 branched before that merge and added the
`CreateChatProviderDisabledRejected` test, which sets `APIKeyID` in a
`CreateOptions` literal. Its CI ran against the old base and passed.
Merged together: `unknown field APIKeyID in struct literal of type
CreateOptions`.
## Fix
Two lines in the test:
- Drop the stale `APIKeyID` field from the `CreateOptions` literal.
- Create the chat owner with `dbgen.User` instead of a random
`uuid.New()`. On current `main`, `CreateChat` resolves the owner's
synthetic API key before the model-config recheck, so a nonexistent
owner fails with `sql: no rows` instead of reaching the
`ErrInvalidModelConfigID` assertion.
## Validation
- `go build ./...`
- `go test ./coderd/x/chatd/...` (full package, passes)
- pre-commit hooks (lint/go, lint/ts)
