fix: show full discrepancy details in account list (#296)

The sync health row displayed "Discrepancies found" but never showed
what the discrepancies were. Parse the stored JSON summary to show
totals (missing locally, missing on server, flag mismatches). Also
wrap the status text in Flexible so long messages are not clipped.
