fly image: add unified SDK; probe reads positions from client.wallet

polymarket-client==0.1.0b16 baked into the worker image (py-clob-client
stays for legacy read paths). Probe: drop the manual-wrap block (bankroll
already converted to pUSD via the bridge — the onramp pauses native USDC)
and stop reading positions from LIVE_FUNDER_ADDRESS (the emptied legacy
proxy); the SDK-resolved deposit wallet is the position holder now.
