Update _ LS Command and Balancing

Fixes

🔹 Fixed Comet group mission counter increasing when completing a simple contract.

Balancing

🔹 Reduced max customers amount to 6 (to avoid too much grind in one night and to keep things dynamic). 🔹 Reduced mining rigs cooldown to 200 seconds. 🔹 Changed the scansystem/scanfolder commands to the ls one. 🔹 Increased even more the ls speed (previously scansystem/scanfolder). 🔹 Increased download/upload speed. 🔹 Increased networks tracer cooldown.
