v5.4: FX trail start 1000 -> 500 pts (metals keep 1000)

100 pips was reachable on metals only — FX winners kept cycle-closing
before the trail engaged (GBPUSD +70 pips Jul 15 had an unmoved SL).
Input renamed InpTrailStart -> InpTrailStartPoints so every chart picks
up the new 500 default on recompile without per-chart preset reloads;
metal presets set it back to 1000 explicitly.
