MarketView

- Added aligned grey markers to price and supply charts to highlight long periods without saved scans.
- Mark gaps over 24 hours in the 7D view, and 48 hours or longer in 30D, All and the Auction House side panel. The 1D view stays unchanged.
- Hover over a gap to see its dates and duration.
- Improved gap-marker spacing and the surrounding price-line and shaded-area edges.
- Added the age of the latest saved scan beneath the main history graphs.
- Clarified graph hover text to distinguish price per unit from available supply.
- Fixed an edge case where a future-dated scan could hide valid price history.
- Added the running client's raw identity to diagnostic reports to make update-related history issues easier to investigate.
