Add a warm charcoal dark mode ("Night Ops") using CSS variable swapping
under [data-theme="dark"]. All 23 desert palette variables are overridden
with dark-mode counterparts, and ~313 generic Tailwind classes (bg-white,
text-gray-*, border-gray-*) are replaced with semantic tokens.
Infrastructure:
- CSS variable overrides in app.css for both themes
- ThemeProvider + useTheme hook (localStorage + KV store sync)
- ThemeToggle component (moon/sun icons, "Night Ops"/"Day Ops" labels)
- FOUC prevention script in inertia_layout.edge
- Toggle placed in StyledSidebar and Footer for access on every page
Color replacements across 50 files:
- bg-white → bg-surface-primary
- bg-gray-50/100 → bg-surface-secondary
- text-gray-900/800 → text-text-primary
- text-gray-600/500 → text-text-secondary/text-text-muted
- border-gray-200/300 → border-border-subtle/border-border-default
- text-desert-white → text-white (fixes invisible text on colored bg)
- Button hover/active states use dedicated btn-green-hover/active vars

Ollama can silently run on CPU even when the host has an NVIDIA GPU,
resulting in ~3 tok/s instead of ~167 tok/s. This happens when Ollama
was installed before the GPU toolkit, or when the container was
recreated without proper DeviceRequests. Users had zero indication.
Adds a GPU health check to the system info API response that detects
when the host has an NVIDIA runtime but nvidia-smi fails inside the
Ollama container. Shows a warning banner on the System Information
and AI Settings pages with a one-click "Reinstall AI Assistant"
button that force-reinstalls Ollama with GPU passthrough.
