Implement automated rent-bumping and on-chain state restoration across all LynxX Soroban contracts (badge, fund, escrow, factory): - Add shared ttl helper crate exposing extend_storage_ttl(), bump(), and bump_instance() with a 30-day extension window (172,800 ledgers) and a 14-day bump threshold (80,640 ledgers). Host only bumps when remaining TTL is below threshold, keeping routine access a free no-op. - badge: bump tier entry + instance/code on every award/query; add public restore_badge(user_id, expected_tier) that recovers an archived badge from verifiable archival proof data, emitting BadgeRestored and rejecting forged proof (ProofMismatch) or unknown donors (NotInitialized). - fund: bump donor contribution entries and contract instance/code on donate/set_badge/withdraw/refund and contribution reads. - escrow: persist lifecycle Status in storage and rent-bump on every transition and read, recovering archived state on access. - factory: keep campaign registry instance/code alive on deploy/read. - Tests: TTL-bump-on-award/query, simulated archival eviction followed by restore_badge recovery without data loss, forged-proof rejection, and escrow/fund TTL assertions. Closes LynxXProtocol#4
