Update TSS tests to use new registration flow (#1026)

* Remove signing integration test

The `register_and_sign` integration test covers the same functionality now.

* Update ETH integration test to use new registration flow

* Get program config test working again

* Delete `test_store_share` test

This isn't relevant in the context of registration anymore. The functionality
of this test was mostly moved to `test_jumpstart_network` anyways.

* Fix `test_fail_infinite_program`

* Fix `test_device_key_proxy` test

* Get `test_sign_tx_no_chain` mostly passing

* Move request limit tests to their own test

* Rename failing signing test

* Move a failing connection test out of `test_sign_tx_no_chain`

* Ignore failing test

Not sure if we still want this, or tbh how to fix it

* Update test name to better reflect what it covers

* Rename `generic_msg` to `signature_request`

This better reflects what the variable actually is

* Fix test for rejecting a TSS node who is not part of the signing committe (#1028)

* Update error message for unexpected participant

* Fix test

* Fix used import and variable warnings

* Use `test_client` for registration in all non-registration tests

* Rustfmt

* Move `update_programs` call to relevant location
