refactor: gas queries

[0xAlunara]

1. Replaces Zustand slices for updating gas prices for each app with a single shared Tanstack query. Greatly reduces deduplicated gas fetching code with slight inconsistencies across the board.
2. All manual fetching (primary in slices) has been replaced by 4 usages of useGasInfoAndUpdateLib({ chainId, networks }) in the layouts of all dapps. In other words, instead of having gas updates sprinkled everywhere, we now have 4 major hook usages on the top level of each app keeping gas info fresh.
3. The query has side-effects; namely that it calls curve.setCustomFeeData() when it fetches gas info. This is not ideal and we'd want to keep queries side-effect free. But I think that refactor is out of scope. I've extensively documented this in comments above the query's queryFactory call. I've also named the query useGasInfoAndUpdateLib with a specific AndUpdateLib part to specify this behavior. A later PR / ticket can be made to extract this side-effect and put it in a proper useEffect on the layout level of the apps.
