Derive a tri-state quotaStatus (ok|unsupported|error) per account so a
provider with no quota API renders as 'no quota' with a healthy dot instead
of an alarming bare dash, and treat unsupported as healthy in deriveHealth.
Switch the analytics endpoint off the CLIProxy snapshot, which freezes
whenever the proxy restarts (usage is in-memory only), and onto the merged
daily/hourly usage the dashboard uses. Recent activity from Claude Code,
Codex, and Droid now shows, and a per-surface breakdown answers where usage
goes. Add lastActivityAt, daysSinceLastActivity, hasRecentData and a 30-day
series; per-account today_cost reads null (unknown) rather than a misleading 0.
