lwip is a submodule of many device firmware repos, but the default URLs
often fail to be cloned. Rewrite those URLs with git config to use the
Github mirror to avoid that issue.

Subject: [PATCH 15/23] test: assert getkeypool returns list before passing to
 importdescriptors

The getkeypool command can return an error dict instead of a list
when the underlying operation fails. Add assertions to catch this
early with a clear error message, rather than having the test fail
with a confusing JSONRPCException about wrong type passed to
importdescriptors.

Subject: [PATCH 17/23] ci, ledger: Pin Ledger app versions for compatibility

Pin app-bitcoin-new to v2.4.4 (tag stax_1.9.0_2.4.4_sdk_...) since
newer versions may be incompatible with Speculos v0.25.10 which is
the last version supporting Python 3.9.

Use shallow clone (--depth 1) for both Ledger apps to speed up builds.

Subject: [PATCH 20/23] test, jade: add 5 minute startup timeout

If the Jade emulator doesn't respond within 5 minutes, fail fast
with an error message instead of hanging until the job timeout.

Subject: [PATCH 21/23] test, bitbox02: add 5 minute startup timeout

Wrap the Bitbox02Client initialization and restore_device() call
in a thread with a 5 minute timeout. This prevents CI from hanging
for 45 minutes when the simulator startup blocks indefinitely.

Subject: [PATCH 22/23] Constrain cbor2 to <5.8

In the Sdist and Wheel test environments, the Jade tests all timed out.

The other tests used a fixed version 5.6 of cbor2 which is why they
were not affected.

Fixes #817
