Added opt-in batching and an initial sync to the New Emails polling trigger:

• Added opt-in batching to the New Emails trigger, dispatching each new email individually or in configured batches; enabling it changes the shape a downstream step receives
• Added an optional Look-back Date input to the New Emails trigger for performing an initial sync of emails. The initial sync begins on the first recurrence and backfills every email received on or after the specified date, seeding each once; later recurrences are unaffected. Leave it empty to start from the first recurrence with no backfill
