Link to Harbormaster build targets from the Daemon worker page

Summary:
Fixes T7370. Two changes:

- Make the default to show nothing, instead of showing all the data. This is a better default because the data is sometimes sensitive. Workers should have to opt in to revealing it.
- For TargetWorkers, link to the target (technically the build, for now, since there's no dedicated target detail page).
