bug: DataRefreshWrapper drops form state and stacks timers

[nanaf6203-bit]

Summary

src/components/dashboard/DataRefreshWrapper.tsx calls setTimeout from a useEffect but has no cleanup, and the wrapper's keyed children remount on each refresh, throwing away form state.

Affected area

src/components/dashboard/DataRefreshWrapper.tsx

Steps to reproduce

Click Refresh multiple times quickly → multiple timeout handles stack, and any active form loses state.

Expected behaviour

Cancel timers on next refresh, conditionally remount via specific keys rather than the entire wrapper, and preserve form drafts.

Acceptance criteria

• Cleanup the active refresh timer.
• Don't remount children unless necessary.
• Tests verifying form draft survives refresh.
