"""Trash — v7.45.5.

Trois régressions couvertes :
1. les routes trash n'avaient AUCUNE vérification de session (le CSRF seul ne
   protège pas : cookie lisible + en-tête forgé) ;
2. la suppression depuis l'éditeur réécrivait ``parent_section='Trash'`` et la
   restauration ne le remettait pas → page invisible en Library/Recents/Private ;
3. ``POST /board/api/trash/empty`` (purge totale) n'existait pas.
