Run Airseeker on polygon testnet

[Siegrift]

In #63 we made Airseeker run locally which was a pretty good e2e test. We use Hardhat though instead of a real chain.

Another step forward would be to run Airseeker with the following:

• Deploy the pushers and signed API on cloud
• Deploy Airseeker on cloud
• Use polygon testnet (deploy neccesary contracts first)

The test should use a higher deviation treshold compared to the previous test to avoid draining the sponsor wallet funds.

The test was completed sucessfully and the pieces ran together for a few days. There were minor errors and issues for improvements, but it was working overall.
