Add ashtray persistence & fixes (#21925)

# Summary

This PR adds persistency to ash trays. This in turn fixes cigarettes
butts spawning a round later in locations where non-empty ash trays were
found.

## Changes

- Add persistence to ash trays and prevent (fixes) cigarette butt
persistence if in an ash tray.
- Fixed cigarette butts not being persistent if the cigarette was put
out on purpose and landing on the floor.
- Fixed loss of registered persistence track on item pickup.
- Fixed persistent tracks when item is held by player.
- Removed all ash trays on the Horizon as their existence is now
persistent. One-time job for operations after merge.
- Fixed matter configuration on `/obj/item/material` not being set
during `set_material()`.
- Fixed persistent trash on space turfs.
- Minor adjustments in SQL/Readme.md.
