fix(mobile): viewport meta tag, swipeable tabs, and accurate title sizing

Three fixes surfaced by measuring the dashboard header in an iPhone
emulation instead of a resized desktop window:

- Serve <meta name="viewport" content="width=device-width"> from
  spa.html when MOBILE_CONSUMPTION_MODE is on. Without it mobile
  browsers lay the page out at the ~980px legacy viewport and none of
  the mobile breakpoints ever match on a real device — the mode only
  appeared to work in resized desktop windows and devtools emulation.
  Gated on the flag so desktop-only deployments keep shrink-to-fit
  rendering on phones; exposes is_feature_enabled to Jinja via the
  common context processor.
- Replace the dashboard tab overflow dropdown with a swipeable tab bar
  on mobile. The "more" menu is a poor touch target and duplicates
  half-clipped tabs; antd's tab nav scrolls natively on touch and its
  ping-edge shadows signal overflow.
- DynamicEditableTitle sized its input from a hidden sizer measured
  before webfonts loaded (fallback metrics ~10px narrower) and never
  re-measured, truncating titles that actually fit; the input also
  rendered at font-weight 400 while the sizer measured at the
  container's 500. Re-measure on document.fonts.ready and inherit the
  container's font weight.

+    not a bug.
+
+    Three routes live under the same ``/api/v1/security/`` prefix but are
+    declared with different slash conventions because they come from different
+    owners:
+
+      * ``login``       -> ``@expose("/login")``        (no trailing slash)

+        canonical URLs (the Embedded SDK depends on them). Werkzeug 308-redirects
+        a request that omits the trailing slash to the canonical slashed URL.
+
+    Unifying the two would either break the documented ``csrf_token`` /
+    ``guest_token`` URLs the Embedded SDK relies on, or require patching FAB /
+    an app-wide routing change. So the divergence is working-as-designed. This
