fix: correct water refraction barrier srcAccessMask to prevent VK_ERROR_DEVICE_LOST

Browse source 
The captureSceneHistory barrier was using srcAccessMask=0 with
VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT when transitioning the swapchain
image from PRESENT_SRC_KHR to TRANSFER_SRC_OPTIMAL.  This does not
flush the GPU's color attachment write caches, causing VK_ERROR_DEVICE_LOST
on strict drivers (AMD, Mali) that require explicit cache invalidation
before transfer reads.

Fix: use VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT + COLOR_ATTACHMENT_OUTPUT
as the source mask so color writes are properly made visible to the
transfer unit before the image copy begins.

Also remove the now-unnecessary "requires FSR" restriction in the
settings UI — water refraction can be enabled independently of FSR.
