Improve Tempo Zone SDK helpers

[Slokh]

Summary

• build on feat(tempo): support current zone portals #4828 instead of duplicating its Zone portal, encryption-key, and deposit-status abstractions
• add encryptedDeposit.prepareRecipient for flows where another contract controls token movement and only needs the encrypted Zone recipient payload
• add requestWithdrawal.prepare for inspecting withdrawal calls and protocol/transaction fees without broadcasting
• separate parent-chain callbackGas from the Zone transaction gas override
• allow receipt polling options on Zone sync actions

Validation

• pnpm biome check --write --unsafe src/tempo/actions/zone.ts src/tempo/actions/zone.test.ts src/tempo/actions/zone.test-d.ts src/tempo/internal/types.ts src/tempo/internal/utils.ts src/tempo/Decorator.ts src/tempo/Decorator.test.ts
• pnpm clean && pnpm check:types
• git diff --check

Notes

• The focused Tempo runtime suite currently stops in the shared local fixture before these tests run: the fixture's eth_getBlockByNumber request returns HTTP 400 during setup. This is independent of the changed actions.
