Faucet Fails to Retrieve Token Amounts Due to Improper Config Loading with `defaultDenom`

[kmlbgn]

Description:

When making a faucet claim request using the ukex token, the faucet fails to retrieve the faucet amount from the configuration. Despite ukex being properly defined in the default configuration, the config loading process seems to overwrite or clear the token mappings.

The issue arises in the way the configuration is being loaded via load.go. Specifically, the method replaces every instance of "ukex" using defaultDenom, and then clears the faucet's token mappings (FaucetAmounts, FaucetMinimumAmounts, and FeeAmounts), leaving them empty.

Error message:

2024/09/09 19:42:05 ERROR: [faucet] Failed to get faucet amount from the configuration

Relevant code locations:

• Config loading:
  https://github.com/KiraCore/interx/blob/8abe867e509a0850fe00fa3bc53725aaaf8db22f/config/load.go#L152
• Faucet failure: https://github.com/KiraCore/interx/blob/8abe867e509a0850fe00fa3bc53725aaaf8db22f/gateway/interx/faucet.go#L225

Other relevant faucet (KIPs):

• ETH Faucet Endpoint
• BTC Faucet Endpoint

Expected Behaviour:

The faucet configuration should no longer delete "ukex" and simply use defaultDenom.
