8b6470a gui: disable top bar menu actions during shutdown (furszy)
7066e89 gui: provide wallet controller context to wallet actions (furszy)

Pull request description:

  Small follow-up to dashpay#751.

  Fixes another crash cause during shutdown. Which occurs when the user hovers over the wallets list.

  Future Note:
  This surely happen in other places as well, we should re-work the way we connect signals. Register
  lambas without any precaution can leave dangling pointers.

f904777 lint: fix custom mypy cache dir setting (Fabian Jahr)

Pull request description:

  fixes bitcoin#28183

  The custom cache dir for `mypy` can only be set via an environment variable, setting the `MYPY_CACHE_DIR` variable in the program is not sufficient. This error was introduced while translating the shell script to python.

  See also the mypy documentation: https://mypy.readthedocs.io/en/stable/config_file.html#confval-cache_dir

Pull request description:

  Various cleanups to the USDT functional tests, largely (but not exclusively) follow-ups to bitcoin#27831 (review). Except for slightly different logging behaviour in "test: store utxocache events" and "test: log sanity check assertion failures", this is a refactor PR, removing unnecessary code and (imo) making it more readable and maintainable.

  The rationale for each change is in the corresponding commit message.

  Note: except for "test: store utxocache events" (which relies on its parent, and I separated into two commits because we may want the parent but not the child), all commits are stand-alone and I'm okay with dropping one/multiple commits if they turn out to be controversial or undesired.

    ACK 9f55773. Reviewed the code and ran the USDT interface tests. I stepped through the commits and think all changes are reasonable.
