* feat: implement exponential backoff for paid_invoices_stream across all Lightning backends
- Add exponential backoff retry logic to CLN REST, LND REST, and LND gRPC backends
- Start with 1 second delay, exponentially increase up to 5 minutes maximum
- Reset delay to 1 second on successful reconnection
- Improve error logging to include retry delay information
- Replace fixed delays with adaptive backoff to handle network issues gracefully
- Prevents system overload during persistent connection problems
Resolves issues with rapid reconnection attempts that could overwhelm Lightning nodes during network instability.
* remove unused import
* feat: extend exponential backoff to all remaining backends and invoice listener
- Implement exponential backoff in LNbits paid_invoices_stream for both SSE and WebSocket modes
- Add exponential backoff guidance comments to Blink and Strike backends (not implemented)
- Apply exponential backoff to invoice_listener in tasks.py that calls paid_invoices_stream
- Ensure consistent retry behavior across all Lightning backend integrations
- Improve system resilience during network interruptions and backend failures
All backends and the invoice listener now use the same exponential backoff strategy:
- Start with 1 second delay, exponentially increase up to 5 minutes maximum
- Reset delay to 1 second on successful reconnection
- Enhanced error logging with retry delay information
