Fix COSS migration regressions (menu group, dialog padding, destructive button, auth form layout)

- MenuGroupLabel must live inside a MenuGroup (Base UI context) — wrap the
  label in nav-user, team-switcher, and nav-notifications. Fixes the
  'MenuGroupContext is missing' runtime error.
- Patient form/detail dialogs: COSS DialogPopup has no inner padding; move the
  body into DialogPanel (form as 'contents') so fields get p-6 instead of being
  flush to the edges.
- Settings 'Delete' button used the default variant + bg override, keeping a
  near-white border-primary in dark mode. Use variant='destructive'.
- Auth forms: COSS Field is items-start (no stretch). Make the submit button and
  the password-row/grid w-full, and underline the bottom sign-in/up link.
