`capi serve --target dev` invalid transactions

[kratico]

capi serve --target dev switches the RPC endpoint but it doesn't switch the dev package. As a result, transactions are sent using the non-dev package metadata. For example, with the following nets.ts, transactions send to the polkadotDev endpoint use version 9420 (which is the version on wss://rpc.polkadot.io/) but the version should be 9380 (which is the dev binary version)

import { bins, net } from "capi/nets"

const bin = bins({ polkadot: ["polkadot", "v0.9.38"] })

export const polkadotDev = net.dev({
  bin: bin.polkadot,
  chain: "polkadot-dev",
})

export const polkadot = net.ws({
  url: "wss://rpc.polkadot.io/",
  targets: { dev: polkadotDev },
})

The same thing could happen if there is a miss alignment in some constants, for example the SS58Prefix.

The solution could be to validate that both networks share the same metadata (or the same constants).

Is this the same as https://github.com/paritytech/capi/issues/1173 or different?

@ryanleecode yes, it's the same as #1173
