Address hardcoded gas in UI or calculate it manually

[judith-Near]

"Given there are a LOT of situations where someone might want to use multisafe TXs to confirm functionCall requests that require 50+ Tgas, I think you should temporarily increase to at least 100Tgas and longer term you can either:

1. Check the request they are confirming and if the gas field is present you can ADD this amount to the default gas amount.
2. Provide a UI option to specify the gas.
   But you cannot continue to send users to the wallet with a fixed default gas amount and no option to increase, because you are sending them into a preventable error and retry scenario. This is bad UX."
