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.
