[BackStacked]

Real logo

Replaces the placeholder drop icon with the real MGPL Diagnostics logo, copied unchanged from mgpl-diagnostics/website.

• public/logo*.svg: the full lockup on sign-in, and the compact one in the header with "Dashboard" from sm up.
• app/favicon.ico and app/apple-icon.png: the website's icons.
• components/Brand.tsx: shows the light or dark file with darkHidden / lightHidden. There are no CSS filters on the logo.

Sign-in without a lab code

• The api finds the lab from email and password, so the Lab code field is gone.
• When one email and password match several labs (ORG_REQUIRED), sign-in shows Choose a lab. The list comes from extensions.organizations (api PR, auth-kit 1.5.0).
• The text field stays as the fallback for an api that doesn't send the list.
• NEXT_PUBLIC_MGPL_ORG_CODE is now empty by default.

Switching labs

• The account menu lists the person's labs (myOrganizations) and ticks the current one.
• Picking another lab calls switchOrganization, with no password; the owner chose this.
• After a switch, every cached query resets and the app goes to Today with a "Now in …" notice.
• Search (Ctrl K) offers "Switch to …" for the same labs.
• lib/labs.ts uses mgpl.request, the same way lib/reports.ts does. So this works on client 1.4 and on an api without these fields; there it shows no switcher. After client 1.5.0 it can move to mgpl.auth.organizations / switchOrganization / organizationChoices.

Depends on (for the lab list and switching only)

• feat: choose and switch organisations for one person (1.5.0) auth-kit#13 (1.5.0)
• the api PR adding myOrganizations, switchOrganization and the pick list
• the client PR (1.5.0), which is optional here

Checks

• typecheck, lint and build pass.
• Logo screenshots are correct in light, dark and phone views.
• Against a mock api with the new schema, on desktop and phone:
  • single-lab sign-in needs no code;
  • two-lab sign-in shows the pick list, and picking a lab signs in;
  • the account menu lists both labs with the current one ticked;
  • switching shows the other lab;
  • search offers the switch.
