PlaceableEntityBase: Entity does not stick on displacements #1881
Description
Possibly a continuation of #1443
I was attempting to check why The Soap did not stick to displacements when I found #1443, out of curiosity I checked C4 too and it's equally as broken
I believe ttt_base_placeable's StickEntity() is not welding again, or at least not on displacements., as it works on 90° walls and what seems to be 45° walls.

Context:
- Map:
gm_construct - TTT Version: Workshop v0.14.6b
- Workshop addons: (On video) TTT2 Base, ULX, Ulib, ULX Commands for TTT2, and The Soap. Reproduced also without any addons but base.

Description:
Entities meant to stick to surfaces with StickEntity() do not on displacements.
Expected behavior:
Stick to any surface, it cannot be picked up with the magneto stick nor moved by explosions or props.
Actual behavior:
It indeed cannot be moved on non-displacements, but it can move on displacements.
Reproduction:
Just stick to any displacement
For a more consistent setup:
- Load
gm_construct - Buy a C4.
- Travel to
setpos 737.069092 1271.803223 -45.271919;setang 53.787880 92.438278 0.000000 - Stick to the ground with Right Click.
- Attempt to pick up with the magneto stick.

I believe I have traced the bug to:
TTT2/gamemodes/terrortown/entities/entities/ttt_base_placeable.lua
Lines 196 to 201 in 30e6b13
It does not hit when on a displacement, and I argue this is because the entity clips a little bit into the ground. Adding
local tr = util.TraceEntity({ - start = pos, + start = pos + Vector(0, 0, 4), endpos = pos - Vector(0, 0, 16), filter = ignore, mask = MASK_ALL, }, self)fixes both C4 and Soap sticking
Disclamer: I first tried Vector(0,0,1), it did not work. I tried Vector(0,0,2), it worked for Soap but not C4, I tried Vector(0,0,4) then it worked for both. If this fix is taken, which seems like a bandaid tbh, a good value needs to be found.
