Revert "Revert change to default reapply type" (#5956)

## What changed?
Change default `ResetReapply` enum value to `ALL_ELIGIBLE`.

## Why?
Reverts #5688, i.e. after this PR we will have the
behavior described in #5360.
This means both signals *and* updates will be reapplied by default
during resets and coinflict resolution, which is the product behavior we
want.

### Explanation
- #5360 attempted to introduce a new proto enum value and start using it
as the default
- However, that is not a valid single-deploy change, since it can cause
a frontend client on the new version to send a value that is unknown to
a history node on the old version.
- Therefore #5688 reverted the change to the default, allowing the new
proto enum value to be introduced to the codebase
- This PR is deployable iff all clusters that we deploy to have #5360
deployed


## How did you test it?
I didn't. Tests were added in the original PR
#5360.

## Potential risks
Could break reset or history conflict resolution.

## Is hotfix candidate?
1.25.1
