chore: update dependencies

[reneleonhardt]

Chores

• Update dependencies
• Let dependabot update docker, github-actions and uv
• Replace update uv.lock workflow with dependabot CI

[reneleonhardt]

It would make contributions easier if CI wouldn't require approval 😉

The old dependabot rules and the update uv.lock workflow weren't functional (no -U), the new ones should work better and use CI before (auto-) merging.
If everything works as expected, non-breaking minor updates could be auto-merged too.

mcp 1.10 is breaking, reverted to 1.9.4:

TextContent(type='text', text="1 validation error for ListToolsResult
tools.0
  Input should be a valid dictionary or instance of Tool [type=model_type, input_value=<AsyncMock id='4763911232'>, input_type=AsyncMock]
    For further information visit https://errors.pydantic.dev/2.11/v/model_type", annotations=None, meta=None)
