feat(federation): 2D/3D projection toggle + interaction fixes + mobile layout polish

- Small glass 2D/3D toggle top-right of the map: tweens tilt/perspective/fit
  (0.9s inOut) so the scene folds flat into the original radial 2D layout and
  back. Default: portrait/mobile opens 2D, desktop 3D; last choice saved to
  localStorage.
- Fix: setPointerCapture retargeted pointerup to the container, suppressing
  click synthesis on children — node taps and the toggle never fired. Drag
  now tracks via window listeners, no capture.
- Fix: stale post-drag distance made the click-suppressor swallow toggle taps
  indefinitely ('stuck' toggle). Distance resets on every pointerdown and the
  suppressor is one-shot.
- Map no longer slides under the floating mobile back pill: the
  mobile-scroll-pad-back panel keeps its full 64px clearance when filled.
- Mobile DID copy/rotate card moved out of the header to below the view tabs
  (new DidCardMobile.vue) and hidden on the Network Map tab.
- Node labels: dark stroke halo removed; 10px on mobile.
