Replace custom log entry rendering (MonoText, Badge, per-entry HTML) with
the LogViewer composite component. Map mock data to LogEntry interface,
remove formatLogTime helper, and clean up unused CSS classes and imports
(Card, CodeBlock, ProgressBar, sectionHeaderRow, sectionTitle, fdRow).

- New /agents/:appId/:instanceId page with process info, 3x2 charts
grid (CPU, memory, throughput, errors, threads, GC), application
log viewer with level filtering, and instance-scoped timeline
- AgentHealth now uses slide-in DetailPanel for quick instance preview
- Stat strip enhanced: colored StatusDot breakdowns, route ratio with
state-colored values, Groups renamed to Applications
- Unified page structure: stat strip → scope trail with inline badges
(removed duplicate section headers from both pages)
- StatCard value/detail props now accept ReactNode
- Log and timeline displayed side by side
