Deploy hook for TPLink Omada Controller

Hello,

Would you mind to integrate the omadasdn deploy hook from [omadasdn](https://codeberg.org/fumbra/acme_omadasdn) for the TPLink Omada Controller ?
Thanks you.

No specific files or tests are named in the issue. Start by finding where acme.sh registers and executes deploy hooks, then compare against the linked omadasdn project to model the TPLink Omada integration point. Add the new hook in the same registration/style pattern used for existing providers and update the relevant deployment hook documentation. A done state is a documented, selectable Omada hook that works through the normal deploy flow.
