Fix: FilterParams was removed in py_clob_client 0.30+ — use keyword args directly

FilterParams was an internal dataclass that got inlined into the client methods in py-clob-client ≥0.30. The fix depends on where you're using it:

If you're calling get_orders / get_trades

# Old (fails on 0.30+):
from py_clob_client.client import FilterParams
params = FilterParams(market=MARKET_ID, asset_id=TOKEN_ID)
client.get_orders(params)

# New:
client.get_orders(market=MARKET_ID, asset_id=TOKEN_ID)
# or using OpenOrderParams:
from py_clob_client.clob_types import OpenOrderParams
client.get_orders(OpenOrderParams(asset_id=TOKEN_ID))

If you're on poly-market-maker specifically

The market_maker.py file in this repo imports FilterParams in a compatibility shim that targets py-clob-client 0.28.x. Upgrade path:

1. Upgrade: pip install py-clob-client==0.34.6
2. Replace any FilterParams(...) calls with OpenOrderParams(...) from py_clob_client.clob_types
3. Note that 0.34.6 also has the order_version_mismatch V2 bug (see issue bug: orderbook refresh thread crashes silently when API fetch fails #87 in this repo and py-clob-client#340) — a V2-compatible fork is needed for production use until an official patch ships.
