fix: crash when spend limit not set

[jim380]

Problem

The application was crashing with the error:

TypeError: Cannot read properties of undefined (reading 'denom')

This occurred when a feegrant was created without a spend limit using the command provider-services tx feegrant grant main X --expiration "Y".

Solution

Added null checks and fallback UI for undefined spend limits in authorization components:

• Added optional chaining for spend_limit access in AllowanceGrantedRow
• Added optional chaining for spend_limit access in AllowanceIssuedRow
• Added optional chaining for spend_limit access in GranteeRow
• Added "Unlimited" display text when no spend limit exists

Testing

• Verified handling of feegrants with no spend limit
• Confirmed display of "Unlimited" text for unlimited grants
• Tested both limited and unlimited feegrant scenarios

Thanks for the contribution. It would be great if you could introduce yourself in sig-client channel, or if you could join a future sig call. Feel free to continue using the product, and share any feedback or any issues in the console repo, or elsewhere.
