v1.2.0 - UI polish & bug fixes

What's new

Bug fixes

• Splash screen no longer flashes gallery behind it during transition
• Nav bar now fully collapses (no leftover empty space) when hidden on Gallery
• Nav bar auto-hide is now Gallery-only; other tabs always keep it visible
• Duplicate images in gallery fixed (rapid scroll no longer triggers multiple concurrent page fetches)

Changes

• Splash is now text-only (removed logo image)
• Favorites removed from nav bar; access it via the Albums tab card at the top
