Endpoint to change which texture is currently in-use for a player's profile

[Sollace]

Currently the only way to switch active textures is to reupload it, which causes duplicated entries in the history.

Switching in-use textures should take the texture_id with some optional ok/fail response and change the timestamps on the history entry for the texture to make it the most recent.

I think you need something unrelated to history. I won't be rewriting history entries.
