feat: Dedupe and invalidate in-flight wallet address fetches

[ashaltykou-innowise]

Summary

• Deduplicate concurrent AddressService.getAddress calls for the same wallet/network/account so only one HRPC request runs.
• Introduce wallet/global epochs (invalidateWallet / invalidateAll) so late responses after delete, lock, or reset do not write stale addresses or loading flags into the store.
• Hook invalidation into wallet delete (useWalletManager) and worklet teardown (WorkletLifecycleService), with unit coverage for dedupe and stale-write skipping.

Test plan

• Run AddressService unit tests (dedupe, invalidateWallet, invalidateAll, fresh fetch after invalidate)
• Delete a wallet while address fetch is in flight — store should not retain addresses for that wallet
• Lock/reset (worklet dispose) while address fetch is in flight — cleared address state should not be repopulated
• Concurrent getAddress for the same key results in a single HRPC call; different keys still fetch in parallel
