test: expand unit test coverage (+437 tests, 17 new files)

Browse Source 
Add comprehensive unit tests for previously uncovered API lib modules,
web stores, and plugin functions. Fix 2 pre-existing editor-store test
failures (invertSelection mask values).

Coverage: 30.3% -> 36.85% stmts (unit), 57.71% stmts (integration).
