Matt be261f3f90 fix(dev-lan): unblock phone-on-LAN testing of the dev server ...

Branding URLs were baked with env.APP_URL=http://localhost:3000 at
upload time and stored verbatim in system_settings, so any logo/
background loaded from a non-localhost origin (an iPhone hitting the
Mac's LAN IP) failed to resolve. Same pattern bit Socket.IO (CORS +
client connection target) and the portal logout redirect.

- Branding: getPortBrandingConfig normalizes localhost/private-LAN
  hosts to path-only; both upload routes store path-only going
  forward; email shell re-absolutizes via absolutizeBrandingUrl() so
  inboxes (no app origin) still get fetchable URLs. DB backfilled to
  strip http://localhost:3000 from existing rows.
- Socket.IO: client connects to window.location.origin (io() with no
  URL); server CORS allows localhost + private-LAN ranges in dev,
  stays locked to APP_URL in prod.
- Portal logout: redirect target built from the request URL instead
  of env.APP_URL.
- next.config: allowedDevOrigins widened from a hardcoded IP to
  192.168/10/172.16-31 wildcards so HMR works across networks
  without an edit per-network. (Without HMR the login form's React
  click handler never hydrates and the form falls back to GET,
  leaking the password into the URL.)
