CW-1086: Polygon Issues (#2329)

* fix(polygon): Polygon wallets not showing in address book when sending tokens

* feat(polygon_issues): Enhance gas price handling in EVM Chains

This change:
- Updates gas price calculation to account for minimum priority fee in Polygon
- Adjusts gas price handling to use maxFeePerGas when gasPrice is not provided.
- Fixes issue with send all for Polygon
