p_switch: P_InitSwitchList omits DEH_String wrapper on texture names

[sunsided]

Context

P_InitSwitchList in room/src/doom/p_switch.rs loads the switch texture table.

C behavior

The C source wraps each switch texture name with DEH_String() before looking it up, allowing Dehacked patches to rename switch textures.

Rust behavior

The Rust port uses the raw texture names without DEH_String, so Dehacked patches cannot override switch texture names.

Location

room/src/doom/p_switch.rs — P_InitSwitchList

Flagged with // FIXME: in the source.

Suggested fix

Route each texture name through DEH_String (or the Rust equivalent) before the texture lookup.
