The pure override in OptimizerInputCapture could not write to storage,
and getLiquidityParams calls calculateParams via staticcall which
prevents both storage writes and event emissions.
Fix: extract the input-building normalization from getLiquidityParams
into _buildInputs() (internal view, behavior-preserving refactor).
The test harness now exposes _buildInputs() via getComputedInputs(),
allowing tests to assert actual normalized slot values.
Updated tests for pricePosition, timeSinceRecenter, volatility,
momentum, and utilizationRate to assert non-zero captured values.
