* chore: Make the Haystack core "type complete"
For libraries with a `py.typed` marker, it is [recommended][1] to
make all public interfaces "type complete", i.e. to explicitly
annotate all function parameters and return types. Doing so has the
following benefits:
- It maximizes the type information available to users and IDEs.
- It ensures that the argument and return types are the intended ones.
- It sidesteps differences in type inference between the different
type checker implementations.
This change makes a first step towards type completeness by enabling
the Mypy `disallow_incomplete_defs` for the core modules (excluding
`haystack.components.*` and `haystack.testing.*`) and fixing the
resulting errors.

* chore: Add `python_version = 3.9` to Mypy config
This catches type constructs that are only supported in later Python
versions.
