feat: improve usability of coder show (#21539)

This PR improves the usability of `coder show`:

- Adds a header with workspace owner/name, latest build status and time
since, and template name / version name.
- Updates `namedWorkspace` to allow looking up by UUID
- Also improves associated `TestShow` to respect context deadlines.
