Add a separate safety toggle for /sethome #6647

Feature description

Could /sethome have a safety toggle of its own? Something like sethome-safety: false would let players save the spot they're standing on. /home and /tpa would still use the usual checks when they teleport someone. The current behaviour could stay the default.

How the feature is useful

On SemiAnarchyMC, players get "The teleport destination is unsafe" when they try to save a home on a bottom slab or the lower step of a stair. We reproduced it on EssentialsX 2.22.1-dev+28-f8724e2 with Leaf 26.3. We saved both spots in dev and tried /home with teleport safety on. It took us back to the slab and moved the stair landing up to the top step. Current save check

force-disable-teleport-safety gets past the save error, but it also turns off safe landing checks for teleports. We carry a small patch just for /sethome. A separate setting would let us go back to the stock build.
