aws: use internal HTTP client

The AWS SDK connector builds a raw reqwest client, bypassing
Vaultwarden TLS, DNS, redirect, proxy, timeout, and request setup.

Construct it through the internal HTTP client interface and retain the
standard ten-second request deadline. Permit private AWS metadata and
service endpoints by disabling non-global IP blocking.

Preserve timeout errors when adapting reqwest failures to the AWS SDK so
the runtime receives the correct connector error category.
