Fixes the workflow editor's fullscreen prompt overlay having an inert-looking mobile Expand button because a static z-index of 10000 sat below the mobile workflow editor's full-screen FloatingWindow sheet (10100+ shared floating-stack band).
- Have the fullscreen prompt overlay claim a fresh shared floating-stack z-index via nextFloatingZ() when opened, instead of relying on the static CSS z-index: 10000 fallback
- Track the claimed z-index in new promptFullscreenZ state, applying it as an inline style on the portaled overlay and clearing it on collapse/Escape
- Update FNXC comments in WorkflowNodeEditor.css and floatingWindowStack.ts documenting the shared z-index contract and why the static value is now only a fallback
- Add regression tests asserting the prompt fullscreen overlay's z-index exceeds the workflow editor's floating window z-index on desktop, mobile prompt nodes, mobile gate nodes, and after re-opening after collapse

Root causes of modals being overlapped + tap-to-front not working across types:
- Only FloatingWindow was portaled; the dock pop-out, terminal, and New Task rendered inline in their own stacking contexts, so the shared z-counter could not order them across types. Portal all three to document.body so all four floating modals share the one root stacking context.
- The floating band started at 4000, below page overlays/popovers at 10000-10001 (log viewer, workflow editor, selection popover, fullscreen overlay) which painted over the modals. Raise the shared band base to 10100. Toasts already sit at 200 (below), unaffected.
- Update RightDock dock-toggle test to the current behavior (popping out closes the dock; the floating modal survives) and fix NewTaskModal keyboard-vars test to query the portaled modal from document.

- Floating modals (FloatingWindow, right-dock pop-out, terminal, New Task) now share one z-index stack (floatingWindowStack) — tapping any one raises it above all others regardless of type. Floating overlays reset to z-index:auto so panels interleave in the shared 4000+ band.
- TaskChatTab tests: the test i18n now resolves the entryCount/toolCallCount plural forms (production already had them) so '2 entries'/'7 tool calls' render; fixed stale 'Tool call → result/error' casing to match the rendered 'Result'/'Error'. All 179 pass.
