Move the version panel out of Help -> Documentation into a dedicated
Settings -> About section. It shows the LoRA Manager, ComfyUI, ComfyUI
Frontend, Python, OS and browser versions, copies the block as Markdown
for issue reports, and links to the issue tracker, wiki, GitHub and
Discord.
Read the values from a new GET /api/lm/environment endpoint instead of
ComfyUI's /system_stats: Python and OS stay available in standalone mode,
while ComfyUI-only versions are omitted there instead of failing the
whole panel. Model Paths is inserted before About so About remains the
last settings section in standalone mode as well.
