Tink 6b3997c463 fix: add from __future__ import annotations across codebase
Ensure all modules using PEP 604 union syntax (X | Y) include
the future annotations import for Python <3.10 compatibility.
While the project requires >=3.11, this avoids import-time
TypeErrors when running tests on older interpreters.
