Add trailing stop to BO EA v5.1 — all 17 presets enabled

ApplyTrailingStop() runs every 5s on open positions: activates after
1000 pts (100 pips) of profit, trails SL 500 pts (50 pips) behind price.
SL only moves in the profitable direction, never backwards.

New inputs: InpUseTrailingStop, InpTrailStart, InpTrailStop (all presets
set to true/1000/500). EA version bumped 5.0 → 5.1.
