Chore/final dealstat version

[ribasushi]

This is what we are using in production. Notable changes are:

• The deallist/filtering are centralized in a single choke point
• The filters evolve as the chain progresses
• Output is augmented with fields requested by frontend + we resolve every client t0 to a full wallet
• Caches are concurrency safe to allow parallel queries
• Remove the envvar: it doesn't really help withhands-free operation
