db unarchive: suggest the group unarchive command when applicable

When a user runs turso db unarchive on a database that's part of a
group, the server returns "database X is part of a group, please
unarchive the group instead" but doesn't tell them how. Look up the
database's group on that specific failure path and append the exact
command (`turso group unarchive <group>`) to the error message,
matching the pattern db_replicate already uses.

Falls back to the bare server error when the lookup fails.

Closes #918.
