Enable KYC verification if the user's spending is above a certain value

[AhmedHanafy725]

• Should calculate the total spending using grid proxy Add endpoint to grid proxy to calculate the user's total spending tfgrid-sdk-go#1058.
• This spending should be only for the main app wallet(the other added wallets shouldn't be included)
• If the spending exceeds the value defined(better to add it to flagsimth), it should enable the kyc verification on the identity tab.
• The identity verification data is stored in the kyc and pkid services
• Try to restore the verification data from pkid or kyc service using the tfchain derived secret. But if that didn't work, we can store the verification ID in the user's metadata on tfchain to get the verification data later from the dashboard.

these will be stored on the backend service instead in the users' table

Facing an issue when trying to get the twin ID from tfchain, the UI is stuck till the call is finished which leads to bad UX.

Facing an issue when trying to get the twin ID from tfchain, the UI is stuck till the call is finished which leads to bad UX.

fixed by using isolated threads to run the expensive calls

Getting another issue when trying to add grid proxy client to the app (can't build the client dart run build_runner build)

Fixed by upgrading the packages and now works fine

The issue is done and ready for review
