- Modified token service URLs to append `includeRwaData=true` for fetching token data. - Updated related test cases to reflect the new API request structure. - Adjusted `TokenListController` to support RWA data in token list retrieval. This change enhances the token service functionality by allowing the inclusion of RWA data in the responses, improving the overall data richness for consumers.

As discussed in slack - we have modified the cache interval from 24 hours to 4 hours.
We should monitor if this causes any performance hits - (mostly from the large writes to state)

I thought we wanted to pass this in constructor client side instead of updating the controller's default values?

meeeeh I don't mind either or... But this would minimise client changes required. Open to options on this :)

Hmmm agree, tbh doing it on constructor seems to be the proper way to go about this.
Doing it in this controller is less changes for sure;
I don't mind tbh, if you feel like you prefer this one, happy to approve 🙏

Sweet, lets do it inside the controller for now -- less changes that devs need to make. We can treat the ones inside the constructor as "overrides" if it needs to be overridden.

We have a PR to update to the new endpoint #7572
However this is postponed to reduce the scope of changes for the RWA feature launch.
