fix(onboarding): correct SHOPPING_LIST id mismatch in navbar favorites

The Shopping List option in the onboarding menu was saved with id 'SHOPPING'
but NAV_ICON_MAP and ProfileView use 'SHOPPING_LIST', causing the navbar to
filter it out and show only 3 items despite the profile reporting 4/4.

Also changes the 4th default favorite from ANALYSIS to SCHEDULED, and adds
a Cypress regression test that verifies onboarding completes with 4 visible
navbar items including the Shopping List selection.

Includes the initial Tauri desktop app scaffold (apps/desktop) and root
workspace scripts for desktop dev/build/install.
