Updated the funding transaction handling logic to send a TxAbort message to peers when signing fails instead of panic. Added a test case to verify that funding is aborted correctly on both nodes when a signing failure occurs.

- Define payment and invoice events to be sent to CCH for both fiber and lnd. - These events can be emitted from fiber store changes in a later PR. - Extract lnd trackers into its own module. - Limit concurrent lnd invoice trackers to 5, scheduling them at 5-minute intervals using a round-robin strategy.

Add gauges to monitor the LND tracker's internal state for better observability. - Track invoice queue length to monitor backlog size - Monitor count of active invoice trackers for capacity awareness - Conditionally compile metrics behind "metrics" feature flag

- When an invoice state changes in Fiber (settled, failed, expired), the CCH order tracking system automatically detects and synchronizes the state without manual polling or intervention. - When an outgoing payment state changes in Fiber (succeeded, failed, pending), the CCH order tracking system automatically detects and synchronizes the state without requiring manual status checks. - CCH monitors invoice for the incoming payment. When CCH has received the incoming payment, it will send the outgoing payment to get the preimage. - CCH monitors outgoing payment to get the preimage and use the obtained preimage the settle the incoming payment.

I don't understand the comment here, PaymentHopData is a molecule type, not a json type.

this is from develop branch, I think we can remove this comment? @doitian
