Bring back the purse gear dropdown (Audio/Discord/Chat/Altre/Filtro) instead of
the tabbed window, and add a 'Gestione Account' item that opens the account
settings window.
Replace the gear dropdown with a single tabbed window: Audio / Chat / Altre /
Account. Audio/Chat/Altre reuse the existing volume + preference controls;
Account recovers UserAccountSettingsView (now embeddable via an 'embedded' prop
that renders its body without its own card). Removes the dropdown menu + dead css.
The purse gear now opens a dropdown (Audio / Discord / Chat / Altre / Filtro
Parole). Audio/Chat/Altre open UserSettingsView focused on that section
(reusing the existing volume + preference controls) with a Back button; Discord
and Filtro Parole are placeholders for now.
