Wei Shi a5784832d0 lib: Add --from-downloaded flag for bootc upgrade ...

Add a new --from-downloaded flag to bootc upgrade that allows users to
unlock a staged deployment created with --download-only without fetching
updates from the container image source.

This provides a way to apply already-downloaded updates without triggering
a fetch operation, which is useful for scheduled maintenance workflows where
the update was downloaded earlier and should now be applied at a scheduled
time.

Usage:
  # Download update without applying
  bootc upgrade --download-only

  # Later: Apply the staged update (without fetching from image source)
  bootc upgrade --from-downloaded

  # Or: Apply staged update and reboot immediately
  bootc upgrade --from-downloaded --apply

The flag conflicts with --check and --download-only as those operations
have different purposes. It can be combined with --apply to immediately
reboot after unlocking the staged deployment.

This commit also updates the documentation (upgrades.md) to describe all
three ways to apply a download-only update, and updates the download-only
test case (test-25) to use --from-downloaded instead of plain
'bootc upgrade' when clearing the download-only flag.
