refactor felinid/chitinid item coughing

[deltanedas]

About the PR

refactored it fully:

• both species use ItemCougherComponent to do the item cough action, with their species components doing only the special interactions
• moved all felinid components to shared, most of its non-duplicate code is still in server though

also changed mouse eating to just automatically happen when you eat a mouse instead of funny action, an event for it exists now

Why / Balance

be felinid
eat mouse with verb
no hairball

Technical details

the species systems use _cougher.EnableAction and handle ItemCoughedUpEvent to do their special logic its not longer shitcode

Media

eating mouse restores the charge for felinid

still cant purge by default

still can purge after healing 30 radiation

Requirements

• I have tested all added content and changes.
• I have added media to this PR or it does not require an ingame showcase.
