fix(security): harden auth flows and lock down telegram bot tool

- config: require JWT_SECRET >=32 bytes and reject the historical
  default fallback; MustInit aborts startup under an insecure config
- api: CORS now uses CORS_ALLOWED_ORIGINS allowlist with safe
  localhost defaults instead of returning Access-Control-Allow-Origin: *
- api: /api/reset-password and /api/reset-account stay public so
  recovery still works, but require an explicit confirm phrase in the
  body to block accidental and drive-by triggers
- api: drop adoptOrphanRecords so wiping the account no longer hands
  the next registrant the previous owner's wallet keys and exchange
  API credentials
- api: getTraderFromQuery now does a soft ownership check; equity-history
  is restricted to traders with show_in_competition=true and
  GetOrderFills joins on trader_id
- telegram: bot api_request tool uses a default-deny method+path
  allowlist so prompt injection cannot reach password, exchange key,
  AI provider or wallet endpoints
- ci: drop @master / @main on trivy-action and trufflehog; pin to
  released versions with a TODO to move to SHA + Dependabot
- web: reset flows send the required confirm phrase; "Forgot account"
  copy (en/zh/id) warns that wallet and exchange keys will be lost
- docker-compose: keep ./.env mount for onboarding wallet persistence
  with an inline note on the tradeoff, drop the host-exposed pprof port
