Set annos as hidden in Elasticsearch based in moderation status

[acelaya]

Before the moderation system was implemented and unanchored threads were introduced, annotations would be marked as hidden only if the whole thread they belong to was also hidden. As soon as one annotation in the thread was not hidden, we would mark the whole thread as not hidden.

This no longer makes sense with the new moderation system. If a parent annotation is denied, but it has approved replies, we want only the replies to show as an unanchored thread, so this PR removes that old piece of logic, making annotations be hidden in elasticsearch only based on their own moderation status.

In the annotation entity, is_hidden is a @property that is computed from the moderation_status.

All failing CI steps are due to the recent update to pip 25.3, which is not compatible with latest version of pip-tools (see jazzband/pip-tools#2252).

I decided to not roll back to pip 25.2, because GitHub reported a vulnerability issue, but if we need to merge this, and since we don't use pip in production, I'll probably downgrade to 25.2 until a compatible pip-tools version is available.

I reverted to pip 25.2 in main to unblock this, but CI is still red. The weird thing is that it works in local dev envs 🤔

It was working locally due to existing .tox dirs. Deleting them and running any CI command produces the same result as in GitHub Actions.

I finally solved it by pinning to pip 25.2 in the tox file #9979, as reverting the update in requirements did not have any effect.
