fix: VK_INDEX_TYPE_UINT32 (was UINT16) + remove unused depth from pipeline

Browse Source 
- vkCmdBindIndexBuffer indexType changed from 0 (UINT16) to 1 (UINT32)
  to match uint[] index data — this was causing black screen
- Removed depth stencil state, depth attachment format, and depth
  rendering attachment from pipeline/renderer (depth buffer still
  created in swapchain but unused)
