Mainnet positions come back priced

Positions in mainnet Blend pools return USD values, drawn from the Reflector feeds that carry the real on-ledger price writes rather than from the view-only aggregators the pools name as their oracle.

• Every mainnet Blend pool is priced, across both Reflector feed protocol versions.
• Each valuation carries its vintage, so you can see which price it used and how old that price was.
