The under sing shutoff valves and or the fill lines to the sink are clogged.Sometimes you can flush the lines and everything will work fine.Other times you need to replace the lines.Be sure to remove the aireator and check the flow first it might be the whole problem.

Can hot water bleed into the cold water line through a sing handle shower body?

Yes, it can also cross through a two handled faucet. Both the hot and cold sides of the faucet must be on and the flow of water must be stopped or greatly reduced on the outlet side of the faucet. This can occur when a hose with a spray nozzle is attached to a laundry tub faucet with the faucet on and the spray nozzle off, or when a shower faucet is on but the shower spray head is off. When another cold water outlet in the system is turned on then the pressure on the cold side of the laundry tub or shower faucet in question could be lowered below the pressure on the hot side and hot water can flow into the cold water side. There are faucets which have integral check valves which prevent this from occurring. WWW.WOODBRIDGEPLUMBING.COM

Why does turning on one faucet cause significant pressure loss in every other faucet in the house?

Turning on one faucet will cause a pressure drop at any other faucet that is running, but you say it is a "significant" drop - that implies that you have low water pressure, period. You might to consult with a plumber to see if anything can be done - if you live in a house with very old steel plumbing pipes, replacing them can make a noteworthy difference (it's not cheap, of course). Or possibly, you have an unusually low pressure system, perhaps a gravity feed system. Installing a water pump will solve any inconvenience, such as the shower almost quitting when a toilet is flushed elsewhere.
