Add regression test for graph paths with spaces

[brosequist]

Summary

• add a regression test for isolated node compute command construction when the graph filepath contains spaces
• verify the generated command keeps the .mg path as one argument after shell-style parsing

Context

The runtime fix for graph paths with spaces is already present on develop in commit da05aae and included in v2025.1.1+. This test protects against regressing the failure reported in #3016, where meshroom_compute received the project path split into extra arguments.

Tests

• pytest tests/test_compute.py -k processChunkInEnvironment_quotesGraphFilepathWithSpaces
• pytest tests/test_compute.py
