Remove FF ci_limit_test_reports_size

See merge request gitlab-org/gitlab!30592

Previously all Git-related exceptions in squash and rebase would quietly
go to `git_json.log`, but these messages should really be tracked in
Sentry and/or `exceptions_json.log`.

In addition, if the squash in progress check failed, the merge would get
stuck. This commit now handles that error gracefully and logs it.

In the future, we can likely remove `git_json.log` altogether.

Resolve member expiration duplicate API call

Closes #204809

See merge request gitlab-org/gitlab!30764

This solves the duplicate API calls from members.js
by removing the additional events being emitted when
a group member's experination date is changed or
removed. The change event doesn't need to get fired
here because it's already being fired by pikaday
in both cases.
