feat(transaction-pay-controller): alternate relay deposit types

[matthewwalsh0]

Explanation

Replace relayDeposit transaction type with predictRelayDeposit or perpsRelayDeposit based on the parent transaction type (predictDeposit or perpsDeposit). Falls back to relayDeposit for unmapped parent types.

Note

Medium Risk
Touches transaction classification used during Relay submission (including batch/post-quote paths), which can affect downstream tracking/metrics if consumers don’t handle the new TransactionType values correctly.

Overview
Relay deposit transactions created by transaction-pay-controller are now typed based on their parent flow: predictDeposit maps to predictRelayDeposit and perpsDeposit maps to perpsRelayDeposit, with a fallback to relayDeposit for all other parents.

This introduces two new TransactionType enum values in transaction-controller, adds a RELAY_DEPOSIT_TYPES mapping used by relay-submit.ts (including in batched and post-quote flows), and expands the Relay submit tests/changelogs to cover the new behavior.
