[protocol] Add repush ttl seconds to admin operation

[misyel]

Problem Statement

Repush ttl seconds value is optionally passed in when a job runs but there is no way to verify the repush ttl seconds for the version afterwards if the value was changed after the run

Solution

Add repush ttl seconds to add version in admin operation so that we can set the field when we create a new version

{
              "name": "repushTtlSeconds",
              "type": "int",
              "doc": "For store version created from repush, indicates the time-to-live in seconds set during the repush",
              "default": -1
}

Code changes

• Added new code behind a config. If so list the config names and their default values in the PR description.
• Introduced new log lines.
  • Confirmed if logs need to be rate limited to avoid excessive logging.

Concurrency-Specific Checks

Both reviewer and PR author to verify

• Code has no race conditions or thread safety issues.
• Proper synchronization mechanisms (e.g., synchronized, RWLock) are used where needed.
• No blocking calls inside critical sections that could lead to deadlocks or performance degradation.
• Verified thread-safe collections are used (e.g., ConcurrentHashMap, CopyOnWriteArrayList).
• Validated proper exception handling in multi-threaded code to avoid silent thread termination.

How was this PR tested?

• New unit tests added.
• New integration tests added.
• Modified or extended existing tests.
• Verified backward compatibility (if applicable).

Existing CI

Does this PR introduce any user-facing or breaking changes?
