Adapt to Indexer 30-day retention (pruning) - v1.27 mainnet

[begonaalvarezd]

With v1.27 the Indexer rolls out the final phase of retention policies. Filtered JSON-RPC queries on data older than the retention period (30 days) will no longer be served: only point lookups fall back to the archival store. Testnet/staging cut is on July 3; Mainnet rollout July 15.

Transaction-by-address queries (FromAddress / ToAddress / FromOrToAddress) are now backed by the archival store since Genesis, so account history is unaffected. What breaks is filtering by transaction kind, input/changed object, and event type beyond 30 days.

Impact overview

• Wallet extension: SAFE, no changes (uses From/ToAddress only).
• Wallet Dashboard: SAFE, no changes (activity, vesting, staking, migration all use address or owned-object queries).
• Explorer: several views degrade to 30 days or break. See Explorer: graceful degradation for pruned filtered queries (v1.27 retention) #244 .
• Kiosk SDK: transfer-policy discovery breaks for old policies, consumed by wallet and names. This is the only true functional regression. See Kiosk SDK: resolve transfer policy by object type instead of TransferPolicyCreated event #245.
