[Bug] Firehose won't auto remove cursor until it's turned off

Bug report

A scenario where firehose endpoint starts lagging. After recovered then firehose stopped ingesting blocks even after graph-node restarts.

Manual fix :

1. Comment out firehose endpoint from config.tmpl file and restart graph-node by running RPC only.
2. After up and running, uncomment firehose config.tmpl (Turn on firehose)
3. Blocks starts ingesting again with firehose.

Hypothesis :

-Firehose won't auto remove cursor when it's turned on
-After turning off firehose, it shows the delete cursor log

Relevant log output

Bắt đầu bằng cách xem xét các thiết lập endpoint firehose trong config.tmpl và tái hiện chuỗi khởi động lại được mô tả trong báo cáo, sử dụng log của EthereumFirehoseBlockIngestor và BlockStore làm điểm bắt đầu. So sánh hành vi khi firehose được bật và khi bị tắt, đồng thời xác minh rằng việc khôi phục không còn yêu cầu phải thủ công comment endpoint và khởi động lại graph-node.
