chore(connect): type only exports

[martykan]

Description

Enforce type only imports/exports to avoid unneeded schemas getting into bundles

where it was bundled to where we didnt want it to happen? also there is a stupid script that was supposed to catch problems like this. wasn't it enough? https://github.com/trezor/trezor-suite/blob/develop/packages/connect-web/scripts/check-inline-build-size.sh#L9

The inline build is fine due to our tree shaking, but if you import connect-web as a module in some external project and use default webpack settings, you will get a quite big bundle.
This is just some initial exploration on how to improve this, still WIP...
