At some moment in the future we want to have contract that will calculate reward per app on chain. For this purpose such contract will need to know overall amount authorized for each application. This PR adds tracking of those values and also one-time function to initialize variables. It's not feasible to calculate current authorized value in contract because we don't have list of all staking providers on chain. updateAuthorizedOverall allows to add or subtract values from current authorizedOverall, it needed in case before upgrading will be any change in authorization amount. Suggested upgrading sequence: calculate authorized amounts right before upgrading, upgrade + updateAuthorizedOverall, in case there is any tx that changes authorization between two previous steps - execute updateAuthorizedOverall again.

Why not directly setting applicationStruct.authorizedOverall, rather than using int96 increments/decrements?

because with just setting value we always can face frontrun tx that will change authorization and now we have to execute one more tx. With addition or subtraction - maximum we need two txs even if one/many will be executed right before upgrade
