fix: commands clear in-progress state + per_type config rebuilt in DB

Two fixes:
1. Any command (menu, salir, etc.) now clears collecting/__foreach/__cap
   meta before executing, so navigation commands are always a clean reset
   regardless of what flow the user was in.

2. DB per_type was empty ([]); rebuilt with correct structure:
   - Type 1: greeting=submenu_subir, menu/inicio/volver → recibir_info
   - Type 2: greeting=submenu_informes, menu/inicio/volver → descargar_informes
   - Type 3: greeting=show_main_menu, inherits global commands
