[cli] Add --only-cached flag to list locally cached images

[larrasket]

Description

Adds a new --only-cached flag to the find command that lists images stored in the local vault cache. This allows users to see which images are available for immediate launch without a network download.

Closes #140

Testing

• Unit tests

I added the following tests:

• DaemonFind.onlyCachedReturnsCachedImages (verifies cached images appear in output with alias/release/OS)
• DaemonFind.onlyCachedEmptyReturnsNoImages (verifies against empty state)

Manual testing steps:

• Run multipass find --only-cached on the local machine and verify:
• If images are cached, they appear with hash, aliases, OS, release, and version
• If no images are cached, the output says "No images found."
• Running multipass find (without the flag) still works as before

Checklist

• I have signed the Canonical CLA
• I have added necessary tests
• I have updated documentation (if needed)
• I have tested the changes locally

Additional Notes

I chose --only-cached to make it unambiguous that it filters results to cached images only (instead of --cached), and I believe that matches --show-unsupported naming style.

Hi @larrasket, thank you for your interest and contribution to the Multipass project!

It's been quite some time since the original issue motivating this change request was made and the team will have to reevaluate what we want to do about it. I will leave the PR open for now, but we may ask you to make some changes.
