unpause: extend time-based windows by the pause duration

[0xdevcollins]

Source: docs/threat-model.md v1.0, DoS.10 (planned hardening).

The 90-day prize-claim window (EventPrizeClaimExpiry, timestamp-based) keeps running while the contract is paused, and claim_prize is pause-gated. A pause that outlasts a window lets start_cancel sweep unclaimed prizes immediately after unpause without winners ever having had a claimable window. Pending manager proposals (17,280 ledgers) and admin rotations (120,960) can likewise expire during a long pause.

• Record the pause timestamp/ledger in pause; on unpause, extend every open EventPrizeClaimExpiry by the pause duration (or simplest: block start_cancel's expiry check for pause_duration after unpause)
• Decide whether proposal expiries should also be extended; document in the runbook if not
• Tests around a pause spanning the window

Hi team @boundlessfi,

I would like to resolve issue #139: extend time-based windows by the pause duration upon unpause.

Implementation Strategy:

1. Pause Duration Ledger Accounting:
   • Store paused_at_ledger when pause is invoked.
   • In unpause, compute elapsed duration pause_delta = current_ledger - paused_at_ledger.
   • Iterate over active time-bound milestones/campaign windows and shift deadline ledgers forward by pause_delta.
2. Edge Cases:
   • Ensure saturating arithmetic (saturating_add) to prevent integer overflows.
   • Verify unpausing does not revive windows that had already legitimately expired prior to the pause.
3. Verification:
   • Add targeted test cases simulating pause -> time passage -> unpause -> deadline assertion.

Ready to submit a high-quality PR with clean formatting and passing tests. Please assign!
