Fix analyzer warnings

Start with the warning suppressions in .editorconfig and select one unchecked analyzer rule rather than treating this as a single change. Run a local build after removing that rule's silence, then address the emitted warnings and verify the build; update the corresponding checklist item when the change is merged.

This is an overarching issue to track analyzer warnings that are currently silenced. To fix a single warning:

1. Remove the warning silence from .editorconfig
2. Run a build locally
3. Fix any warnings that are emitted
4. Create a pull request
5. Link it to this issue
6. Once merged check the relevant box below
