Implemented performance optimizations in `SMC_TrendBreakout_MTF_EA.mq5`:
- Pre-calculate constants in `OnInit` to avoid redundant divisions and math in `OnTick`.
- Optimize `NormalizeLots` to use multiplication by a cached inverse `G_INV_VOL_STEP`.
- Consolidate risk and point-value math into cached multipliers (`g_riskMultiplier`, `g_lotValuePerUnit`).
- Use pre-calculated SL/TP buffers (`g_swingSLBuffer`, `g_fixedSL`, `g_fixedTP`) in the execution path.
These changes reduce CPU overhead during rapid market ticks without altering trading logic.
