Restructure application to use /home for authenticated pages

- Move authenticated home page from /[locale] to /[locale]/home
- Move login page from /[locale]/login to /[locale] (new landing page)
- Move all restricted pages (bill, location, year-month, print, account) under /[locale]/home
- Simplify middleware to protect all routes under /home instead of using publicPages array
- Update auth config: change signIn page from /login to /
- Update SignInButton callback URL to redirect to /home after login
- Update all internal links throughout the application to reflect new structure
- Update server action redirects in navigationActions.ts
- Public share routes (/share/*) remain unchanged
