Increase Large/XL font sizes, enlarge account switcher, fix relay drop and bookmark persistence

- Large font 16→17px, Extra Large 18→20px
- Account avatar w-8→w-10, name and arrow text larger
- resetNDK preserves outbox-discovered relay URLs instead of dropping to fallback 3
- BookmarkView merges relay results with cache instead of replacing, so cached notes survive timeouts
