fix(issues): Add typing to around event_frames (#97898)

# Summary
I picked up [SENTRY-45X5](https://sentry.sentry.io/issues/6731943173/)
on a lark. It seems like we're somehow getting `event_frames` full of
`None` returns. While trying to figure that out, I jumped around and
typed every instance of `event_frames`. Figured it'd be better to put it
up as a PR than not.

# Test Plan
Only changes are typing changes; `mypy` no errors.
