chore(core): use `T | None` instead of `Optional[T]`
[no changelog]
What changed, and why it matters
This is a minor code cleanup that changes how optional types are written in one Python file. It replaces the older `Optional[Type]` style with the newer `Type | None` style. There is no functional change and no security relevance.
No action needed. This is a non-functional style-only change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit modifies type annotations only under a TYPE_CHECKING guard in core/src/trezor/wire/__init__.py. It removes the Optional import from typing and rewrites three parameter annotations (exc_type, exc, tb) from Optional[T] to T | None. These annotations are not evaluated at runtime and do not alter program behavior.
