feat: rework runtime charts and fix time range propagation

Runtime page (AgentInstance):
- Rearrange charts: CPU, Memory, GC (top); Threads, Chunks Exported,
  Chunks Dropped (bottom). Removes throughput/error charts (belong on
  Dashboard, not Runtime).
- Pass global time range (from/to) to useAgentMetrics — charts now
  respect the time filter instead of always showing last 60 minutes.
- Bottom row (logs + timeline) fills remaining vertical space.

Dashboard L3:
- Processor metrics section fills remaining vertical space.
- Chart x-axis uses timestamps instead of bucket indices.
