EPIC: connect 10 - tracker

Lets start with:

marking places in code that require refactoring but it comes at the cost of introducing breaking changes with a comment
```
// todo: connect10
```
at the same time, if breaking change should be introduced in connect 10, lets put a deprecation warning where it makes sense.

Lets start listing future breaking changes here:

### Future breaking changes
- [ ] remove `connectSettings.webusb`
- [ ] remove workarounds in poup.html (cc @martykan, please edit)
- [ ] device.state string to object - https://github.com/trezor/trezor-suite/pull/12887
