Neftlix 0.5.5

Changed

• Discreet categories are hidden by default: they and the titles filed only under them are left out of Film, Serie TV, Live TV, search, the home rows and "Random" (a title that also sits in a normal category stays visible). A new "Categorie riservate" panel in Impostazioni shows them again for the active profile only; every other profile keeps its own choice. Saved favourites and "Da guardare" keep their titles either way; the no-trace rules from 0.5.0 still apply when they are shown. Database: profile.show_discreet (automatic migration), PATCH /api/profiles/:id accepts showDiscreet.
