Sanity checked yarn env app config:

✅ No THORChain swapper available

✅ Savers deposit and withdraws disabled

❌ Lending & Pools routes are gone. This is not ideal, and too course of a flag - users should still be able to view their positions.

Nice catch @0xApotheosis! Reverted the top-level flags and only kept the granular ones in a1cb69d

Much better 🙏

Positions are accessible, but can't be interacted with. Exactly what we want!
