Add a "Global Max Concurrent" slider to the footer engine menu and the
Command Center Concurrency card, and group the Scheduling settings by
Global vs Project scope so the global cap isn't mistaken for a per-project
setting (clearer on mobile).
Both sliders are backed by a single shared `useGlobalConcurrency` hook
(module-level store) so they read/write one source of truth and revalidate
after every PUT /api/global-concurrency — fixing the last-writer-wins and
stale-clobber races a per-component cache would cause. The hook treats a
fetch error as non-interactive (slider disabled, not stuck at 1), surfaces
a save-state indicator, and flushes a pending edit on menu close / unmount
so a quick drag-then-dismiss is never silently dropped.

Keep the footer engine controls popover opaque by using valid dashboard CSS tokens.
- Replace the undefined elevated surface token with the solid card surface.
- Align disabled action opacity, range accent, and mobile height CSS with defined tokens/values.
- Add a CSS token regression test for the engine control menu popover.
