Fix Omada package version extraction

Update both `ct/omada.sh` and `install/omada-install.sh` to parse the Omada version directly from the `_v..._linux` segment of the Debian filename. This removes the old dependency on a timestamp suffix format and ensures `.omada` gets a valid version when TP-Link package naming varies.
