fix(strategy-ui): correct rankings, currency, injection view and staleness

- MaxDD ranks shallower drawdowns first (values are negative); ruined
  results are badged and never ranked as best.
- Metrics render '—' for null/non-finite values instead of crashing.
- Amounts use the market's currency (CNY for CN) instead of hard-coded USD.
- Injection scenarios show invested / final value / profit / return on
  invested from capitalFlows and label return metrics as time-weighted.
- Precomputed results show their data end date and warn when older than 7
  days; live strategies warn when not updated for 4 days, show start date,
  price as-of, stale holdings, and same-window benchmark with excess return.
- Unknown precomputed scenario returns 400 instead of silently serving the
  first scenario; the client uses the scenarioId it receives.
