fix(jobs): remove non-functional OBO support

[pkosiec]

Closes #515.

The Jobs plugin shipped an on-behalf-of-user (OBO) path via .asUser(req). It never worked: Databricks Apps has no jobs OAuth scope, so .asUser(req).runNow() always fails at request time.

What changed

• Removed .asUser(req) from the jobs plugin
• Removed the JobHandle type; jobs("etl") now returns JobAPI
• Removed the OBO tests and docs

Jobs still run as the app's service principal, same as before. The shared Plugin.asUser() used by other plugins is untouched.
