chore(core): drop duplicate `TypeVar` definition
[no changelog]
What changed, and why it matters
This commit removes a single duplicate TypeVar definition in a Python file used only during type checking. It has no effect on the actual running firmware and no security relevance.
No action needed; this is a benign code-cleanup commit.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change deletes T = TypeVar("T") from a TYPE_CHECKING block in core/src/trezor/wire/context.py. This variable was already defined elsewhere and was unused/duplicated. Because it sits inside an if TYPE_CHECKING: guard, it is not executed at runtime and cannot affect firmware behavior, memory safety, or security boundaries.
