Delete Printer: a queue that's already gone is a successful delete

Judge the delete by the read-back (is the queue gone?) instead of lpadmin's exit
status. Deleting a queue that was removed elsewhere before the sidebar refreshed
made lpadmin fail with 'The printer or class does not exist', and the app showed a
failure alert although the queue was gone. Now the status bar shows 'Deleted <queue>'
and os_log notes it was already deleted. Unit tests for all four outcomes, plus an
opt-in live test (CUPSKIT_LIVE_DELETE=1) on a name that never existed.

 ### Adding your printer's driver
 
 1. `cupsadmin ppdreport <queue>` (or `ppdreport <file.ppd.gz>` for a PPD from a driver package you haven't installed — `pkgutil --expand-full` it first) lists every option your driver has; find the color, duplex, paper and accounting/user-code keywords and their choice values.
 2. Copy the `ricoh` entry in `Sources/CupsKit/Resources/driver-profiles.json`, give it an `id`, and set `match` to regular expressions for your PPD's `Manufacturer` and `NickName` (both are printed at the top of the report).
-3. Replace the `keyword=value` pairs. `{value}` is the code the user types; typed options take `Custom.{value}`. Leave out actions your driver can't do, or explain why under `unavailable`. Keep your profile above `generic`.

Keep your profile above `generic`.
 4. `swift build && .build/debug/cupsadmin ppdreport <queue>` shows which quick actions are now available; try one with `cupsadmin quick`, then open a pull request.
