This commit adds an endpoint to batch the sending of messages.
This is useful to simplify client logic when sending a batch of messages
and ensuring the correct order in the message stream.
It currently implements only what's needed, and naively return an error
if any of the messages fail.
We were not actually passing the topics in the request, therefore we
were using bloom filter for query, which resulted in long syncing times
for some users.
For some reason when calling saveChat from desktop with `lastMessage`
set to null, a sigsev is received.
The issue seems to be in logFormat
05280a7ae3/log/format.go (L356)
which for some reason blows up if passed a nil pointer (`lastMessage`).
Can't replicate on any other platform or running it locally, but hey,
this fixes the issue.
Currently ENS are verified explicitly by status-react, this is not ideal
as if that fails it will have to be explicilty retried in status-react.
This commits changes that behavior so that ENS are verified in a loop
and updated if new messages are received.
