Erik Grinaker 5bdba70f7d page_api: only validate Protobuf → domain type conversion (#12115) ...

## Problem

Currently, `page_api` domain types validate message invariants both when
converting Protobuf → domain and domain → Protobuf. This is annoying for
clients, because they can't use stream combinators to convert streamed
requests (needed for hot path performance), and also performs the
validation twice in the common case.

Blocks #12099.

## Summary of changes

Only validate the Protobuf → domain type conversion, i.e. on the
receiver side, and make domain → Protobuf infallible. This is where it
matters -- the Protobuf types are less strict than the domain types, and
receivers should expect all sorts of junk from senders (they're not
required to validate anyway, and can just construct an invalid message
manually).

Also adds a missing `impl From<CheckRelExistsRequest> for
proto::CheckRelExistsRequest`.
