Preview resolution fixes

Playtest Room

• Preview and Peek is now full resolution. The preview and peek overlay looked more aliased and pixelated than the same card on the table.
• Minimap mask shapes are corrected. Components using a custom or default library mask (hexagons, the star, your own masks) showed as stretched boxes on the minimap. They now show their real silhouette.

General

• Various fixes. Some stability fixes across the site and imports
