Fetch all params on drone connect

[1Blademaster]

Also refactor controllers to use cached params, update tests

[Copilot]

Pull request overview

This PR shifts the radio backend to fetch the full parameter set during drone connection, then refactors multiple controllers to use the cached parameter set (instead of on-demand param reads). It also updates/extends the radio test suite to validate the new cached-param behavior and the new blocking fetch path.

Changes:

• Fetch all parameters as part of Drone initialization and expose progress updates during connect.
• Replace various controllers’ “fetch from drone” param reads with cache-only reads via ParamsController.getSingleParam().
• Update/add tests to reflect the new cache-first controller behavior and the new refresh/fetch flow.

• getSingleParam takes a single param id/name, but the argument is named params (plural) and the docstring says Optional[str] even though the function expects a str. Renaming the parameter to something like param_id (and updating the docstring accordingly) would make the cache-only semantics clearer and reduce confusion at call sites.

    def getSingleParam(self, params: str) -> Union[CachedParam, dict]:
        """
        Get a single parameter from the cached params.

        Args:
            params (Optional[str]): The name of the parameter to get
        """

This is so fast in comparison and proves it was so worth doing. Found a couple of things for you to look at though.
