fix: handle EGL surface creation failure gracefully instead of aborting

Browse source 
When GPU VRAM is exhausted, eglCreatePlatformWindowSurfaceEXT and
wl_egl_window_create can return null. Previously this triggered
RASSERT -> std::abort(), crashing hyprlock and leaving the session
in a broken lock state.

Replace RASSERT with error logging and early return, setting
readyForFrame = false so the next configure event retries the
allocation. This allows hyprlock to survive transient GPU memory
pressure rather than crashing.
