Porting to python3.13 and the latest packages

[philion]

Migrating python to the latest v3.13, and updating all the packages. All test cases working.

The specific problem, that required a lot of experimentation, was a non-mocked method that should have been auto-mocked with an AsyncMock, but got a MagicMock instead:

    def mock_context(self) -> ApplicationContext:
        ctx = mock.AsyncMock(ApplicationContext)
        ctx.bot = mock.AsyncMock(NetBot)
        ctx.bot.redmine = self.redmine
        ctx.user = mock.AsyncMock(discord.Member)
        ctx.user.name = self.user.discord_id.name
        ctx.user.id = self.user.discord_id.id

        ctx.respond = mock.AsyncMock()

        return ctx

ctx.respond = was the solution, essentially pre-populating that method call with an AsyncMock.
