fix(api): repair pre-existing typecheck and lint failures in the TS carve-out

- config.ts: std@0.220 dotenv exports load, not config; drop removed
  allowEmptyValues option
- repository.ts: type the Promise.all destructure (profiles as
  ProfileRecord[]); make uniqueBy generic instead of any
- verisimClient.ts: await the wrapped requests (require-await)

deno task check now passes end-to-end; these errors predate engine v2
(the check task died at the first one, so lint had never run).
