fix: harden CLI export without OpenGL thumbnails (#13532)

Browse Source 
## Summary
- skip CLI thumbnail generation when an OpenGL/GLFW context cannot be
created, allowing export workflows to continue in headless/automation
environments
- guard filament variant remapping against missing config options and
out-of-range variant indexes
- log warnings instead of dereferencing invalid config state during
CLI/profile-driven export

## Context
These guards came out of automating OrcaSlicer CLI exports for printer
workflows. In that flow, slicing/export can still be valid even when
thumbnail rendering is unavailable, but the current path can proceed
into OpenGL thumbnail setup after context creation fails. Separately,
malformed or mismatched filament/profile state can index past option
vectors during multi-filament value remapping.

## Test plan
- `git diff --check`
- `cmake --build build/arm64 --config RelWithDebInfo --target OrcaSlicer
-- -j4`
