fix: let self-hosted servers handle images in tool returns

Browse Source 
The Read tool was gated behind isLettaCloud() for image support,
but self-hosted servers can handle base64 images too with the right
server-side patches (converters.py + message.py).

Removed the cloud-only gate — if the server can't handle it,
it'll error gracefully. Better to try than to silently omit.
