chore: Remove shared::bad_token

[MartinquaXD]

Background

Once the driver side bad token detection is working with high confidence we can remove the shared::bad_token module and all the code that becomes unused by that.

Things to remove or adjust:

• shared: bad_token module
• autopilot / orderbook: token owner finder code
  • baseline liquidity
  • alerts for failing token owner finder APIs
  • CLI args for token owner finding APIs (e.g. blockscout, ethplorer)
• shared::price_estimation::sanitized: bad token handling
• autopilot::solvable_orders: order filtering based on bad tokens
