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.

Command Center concurrency controls now preserve persisted scheduler values and improve mobile slider handling.
- Load concurrency defaults from project settings and display persisted values without clamping the readout.
- Expand range slider maxima when existing settings exceed normal UI bounds while keeping edits bounded.
- Add mobile touch-drag affordance styling and regression coverage for actual values, overflow values, and CSS contracts.
