ekke d8ddbbc910 Fix stale district + offline-safe logout; GPS UTM format; touch-cursor gating; SW v12
Session / district correctness
- public/index.php: add a /?logout=1 endpoint that destroys the PWA's own PHP
  session (session_destroy + expire PHPSESSID + clear sso_auth_token, then
  redirect to the SSO portal). Logout previously cleared only the SSO cookie,
  leaving the PHPSESSID session — and its frozen district_id — intact, which is
  why a reassigned user kept loading the old district across logout/login.
- SSO token is validated once per session, at login (unchanged first-login
  logic). A district transfer is now picked up on the next logout→login, which
  is correct precisely because logout finally tears the session down. No
  periodic SSO polling.
- main.js: the menu Logout button routes through /?logout=1 and wipes
  district-scoped local caches first. Logout is blocked while offline — a
  session can only be created online, so an offline logout would strand the
  user with no way back in (and would not actually reach the server).
- main.js: enforceDistrictConsistency() clears district-scoped caches when the
  session district changes between loads; the district boundary is cached under
  a per-district key (district_boundary_<id>) so one district's geometry can
  never be served for another.

GPS coordinate format
- New "GPS Coordinate Format" setting (Lat/Lon · UTM · Both) in the Settings
  panel; the navbar read-out renders the chosen format and repaints the current
  fix immediately on change. Self-contained WGS84→UTM converter in
  geo-utils.js, verified against an independent Redfearn-series implementation.

ol-ext touch cursor
- MapView gates the TouchCursor to genuine touch-only devices via matchMedia
  (any-pointer: fine / any-hover: hover); hybrid touchscreen laptops keep the
  normal cursor. Reactive to pointer-capability changes.

- Service worker v11 → v12 (new shell). docs/SSO_Session_Refresh_Proposal.md
  documents the implemented approach.
