v5.3.1

• Nado (Infinity DEX) balance fix: Wallet balance and available margin were showing incorrect values — sometimes negative — due to two compounding issues: isolated position collateral was excluded from the wallet total, and oracle divergence between the engine and indexer caused equity to drift during sharp moves. Both are now corrected: isolated collateral is fetched and added back, and the total is calculated from holding-only entries so uPnL is no longer double-counted.

• Market panel missing fields restored: The funding countdown now displays correctly when the remaining time is under one hour (e.g. "5m 30s" instead of blank or incorrect output). Predicted funding rate, funding timestamp, index price, and mark price are now properly passed through to the market info panel and displayed.

• Privacy mode: HIP-4 outcome position size hidden: Outcome market position sizes (notional value and share count) were remaining visible when privacy mode was active. They are now obscured, consistent with how regular position sizes are handled.

• Settled outcome markets auto-switch on load: If a chart or trading widget was saved with an outcome market that has since settled and been removed from the API, it now automatically selects the first available live outcome market on load instead of showing a blank panel.

• Fills on chart: performance and toggle correctness: Multiple chart widgets displaying the same contract would each trigger a separate fills reload on boot, causing redundant network requests. These are now coalesced. Additionally, disabling the "fills on chart" setting now correctly clears existing fill markers from the chart immediately, and no longer draws fills when the setting is off.
