CCM-17640: Delete TTL faster

[Ian-Hodges]

Description

Update to the nhsapp-status-handler function to delete TTLs faster.

• Rename to core-status-handler
• Add support for paper_letter_opted_in event (delete TTL, send Read event).
• Add support for supplierStatus is "rejected" and channelStatus is "failed" (delete TTL, send Unsuccessful event).
• Add support for message.status.PUBLISHED.v1 events where the messageStatus is "failed" (withdraw TTL, send Unsuccessful event).

This PR also includes changes ported over from CCM-17639, and some fixes for flaky component tests.

Context

We currently wait 24 hours for the TTL to be deleted before we send a request for a letter to be printed. However there are several scenarios where we can delete the TTL immediately and speed the process up.

Type of changes

• Refactoring (non-breaking change)

I believe we need to up the version of the PACT contract in pact-contracts/package.json as well.
