When I open the app as a connected user, the inbox is fetched twice

The `/inbox` and `/inbox?page=1` endpoints are fetched twice.

This may be related, but when someone sends a message to my inbox, it is displayed twice (if it has been fetched through websocket -- the message appears only once if I reload the page).

Any idea of where this issue may come from @Laurin-W ?

Reproduce with a connected user and open the `/inbox` flow in devtools to confirm duplicate `/inbox` and `/inbox?page=1` calls. Start by tracing where the inbox screen is mounted and how it triggers API fetches on page load, then check websocket listener setup for the same screen/session to spot duplicate subscriptions. Validate by sending/reloading and ensuring only one fetch sequence and single message render. Finish when no duplicate fetches or duplicated rendered message remain.
