Add dedicated /mcp-tools page for managing MCP servers and tools from the
workbench. Includes CRUD dialogs, config API integration, and feature flag
gating via mcpTools switch. QA pass also fixes accessibility across existing
pages: aria-expanded on chat phase blocks, tabpanel tabindex on prompts,
toggle contrast ratio (WCAG 2.1 SC 1.4.11) on settings.

Three QA iterations to convergence (zero issues remaining):
Workbench UI:
- Connection badge: amber "Connected (no auth)" for unauthenticated state
- Theme persistence: restore script in index.html + localStorage sync
- Settings About section: add bottom padding so content isn't clipped
- Clear messages: cancel in-flight requests when clearing chat
- Feature switch labels: proper casing + acronym handling (MCP, LLM)
- Token Cost badge: hidden during loading state
- ARIA: role="switch", aria-checked on toggles, aria-labels on buttons
- ConfigApi: null-safe chaining for getPrompts/getSystemPrompt
Grafana dashboards:
- Auto-refresh 30s on all 3 dashboards
- Panel heights reduced to fit viewport without scrolling
- Anonymous role upgraded to Editor for Explore access
Infrastructure:
- Nginx: DNS resolver with variable-based upstream (prevents crash loop)
- Workbench port set to 3002 in .env
