* Improve bedsheet interactions (#84505)

## About The Pull Request

This pr simply adds drop/pickup sounds to bedsheets, replaces its
`attackby(...)` and `attack_secondary(...)` with `item_interaction(...)`
and `interact_with_atom_secondary(...)`, and makes tucking in match the
bedsheet `pixel_z` with that of the living we're tucking in. It also
removes a check that's no longer needed to allow for telekinetically
tucking someone in.

First bit of note, we use `item_interaction(...)` instead of
`wirecutters_act(...)`/`tool_act(...)` as I think tearing up the
bedsheets should be the interaction in combat mode too, and everything
under `tool_act(...)` only gets called with combat mode being off.

Second bit of note, we remove the `!user.CanReach(target)` check from
tucking people in, as I believe that's no longer necessary here. This
allows us to tuck people in telekinetically, given the bedsheets are
adjacent to the one we're tucking in.

Finally, we match the bedsheets' `pixel_z` with that of the living we're
tucking in by setting it directly, and also reset it directly when we
smooth the sheets.
I know the elevation element exists, but I believe that only cares about
living instances, and besides that really we only want this to be set
when tucking someone in rather than always. Most importantly, it works.
## Why It's Good For The Game

Using the new item interaction code is better than `attackby(...)` and
such.
Cloth sounds are nicer than no sounds, and make sense given they're,
well, cloth.
Tucking someone in with telekinesis is funny.

Previously, bedsheets would not offset their `pixel_z` to match that of
the living they're tucking in, meaning if you were to say rest upon a
table the bedsheets would always be awkwardly offset.
This fixes that.
## Changelog
:cl:
code: Moved bedsheet interactions to the item interaction code. Please
report any issues.
fix: Bedsheets adjust their offset to match that of the living they're
tucking in.
sound: Bedsheets use the cloth drop/pickup sounds instead of being
silent.
qol: You can tuck someone in telekinetically.
