fix: use net inventory lots in trade profitability analyzer

Buy lots now store net receives (baseAmount − marketFeeReal), so
inventory matching reflects what the account actually held. The fee
allocation denominator is also net, matching the net lot basis.

## Key changes
- `analysis/trade_profitability.ts`: lot amount and fee alloc denominator
  use net base; restored `effPrice` on lot/realized PnL for correct cost
  basis; added EffBuy column to `--trades` detail output; skip fills
  with unresolved fee precision instead of silently setting fee to 0
- `tests/test_trade_profitability_fees.ts`: updated all fee test
  assertions to net-lot math (fee denominator, unmatched sell base,
  net position)

## Testing
- `node --import tsx tests/test_trade_profitability_fees.ts` — all pass
- full `npm test` suite — clean
