tendermint-proxy: 🧼 inherit workspace settings, tidy manifest

inherit settings in the package manifest from the workspace.

remove `default-features = true` directives while we are here. they are
*default* featues, this only needs to be explicitly turned *off* via
`default-features = false`.

we also tidy up the dependencies while we are here.
