feat: support multiple source files in mgrctl cp (Fixes #657)

Allow passing multiple source file paths to `mgrctl cp`. The last
argument is treated as the destination. All sources must be
consistently either local paths or server: prefixed paths; mixing
is not allowed.

Update the Use string and Long description to reflect the new
multi-source behavior. Add validation to reject mixed local and
server source paths.
