Subject: [PATCH] chore(network): add workspace lints to network

Lior banned `as` repo-wide, unless absolutely necessary.

Nearly all as uses can be replaced with [Try]From which doesn't have
implicit coercions like as (we encountered several bugs due to these coercions).

Motivation: we are standardizing lints across the repo and CI,
instead of each crate having separate sets of lints.

Note: i left the `as f64` since `gauge!` expects f64, even though the
metrics themselves are integers. This is probably fixable by using
`counter!` instead of `gauge!`, but i haven't found anyone who knows how
to test these metrics so i'm leaving it for now.
I left them at the statement level intentionaly, instead of the module level,
so that it won't be forgotten.
