Optimized the `CalculateLots` function in `SMC_TrendBreakout_MTF_EA.mq5` by:
1. Pre-calculating the inverse of `SYMBOL_MARGIN_INITIAL` in `OnInit` to replace division with multiplication.
2. Refactoring the logic flow to apply margin constraints before normalization and clamping.
3. Consolidating redundant `MathFloor`, `MathMax`, and `MathMin` calls into a single execution path.
This reduces the computational overhead of lot sizing, especially when margin limits are approached, and improves code readability.
