claude-owner d6fc9d8a0b feat(symbol-page): intraday short-term returns + hline storage-failure guard ...

  (PeriodReturns labels lie when interval is 10m; swap them out by isIntraday)
- addLine/removeLine/clearLines now return previous state when localStorage
  write fails — UI no longer diverges from storage in locked-storage env

addresses reviewer 318eae6 non-blocking caveat about write-failure divergence
