Initialize pair configs from dashboard

Proof: npm test; npm run operator-dashboard:build; focused regressions cover maker/taker activation creating config, invalid initial edge rejection, and invalid max-notional rejection.

Assumptions: Adding maker/taker/both mode should create an initial pair strategy config with operator-provided edge and max notional, but pairs without a real price route must remain blocked.

Still fake: No BTC/USDC external reference price route or liquidity model exists; non-nBTC/EURe pairs still fail closed on missing price route until that path is built.
