[Advanced Permissions] getSupportedExecutionPermissions chainId should be `number` type

[AyushBherwani1998]

Description

Currently the getSupportedExecutionPermissions action returns the chain ids in the Hex format which is inline with the new ERC-7715 spec. For external developer facing, we should return the chain ids in number since viem/ wagmi handles the chain ids in the number

This makes the checks much easier for the developers.

Current response

{
  "native-token-stream": {
         "chainIds": [
            "0x1",
             "0xa",
         ],
         "ruleTypes": [
             "expiry"
         ]
    }
}

Expected response

{
  "native-token-stream": {
         "chainIds": [
            1,
            10,
         ],
         "ruleTypes": [
             "expiry"
         ]
    }
}

edit: the chainIds should be number format, not bigint
