Implement automated check to detect unintended increase in network request volume

[chloeYue]

What is this about?

We've identified a release-blocking issue where a periodic polling task continues to run every 20 seconds, even after the UI is closed. This results in generating a big amount of unnecessary API request to Etherscan and to the RPC provider:

API request to Etherscan:
https://api.etherscan.io/api?

3 to RPC provider:

"jsonrpc":"2.0","method":"eth_blockNumber",
"jsonrpc":"2.0","method":"eth_getBlockByNumber"
jsonrpc":"2.0","method":"eth_call","params":

The objective of this ticket is to introduce an automated check that monitors for unintended increases in the volume of network requests. For example, the test can establish a threshold for network requests and trigger an alert if a significant increase is detected.

This automated check will serve as an early warning system to prevent potential performance issues or unnecessary load on external services, ensuring our application maintains optimal efficiency and resource usage.
