refactor(view): getLocalFile path handling

[joshtrichards]

• Resolves: #

Summary

🧹
The previous getLocalFile() logic worked, but used less-intuitive parent extraction and duplicated resolution steps. It now uses View's resolvePath() rather than duplicating logic.

Also adds type hinting for and clarifies resolvePath and getAbsolutePath() contracts.

This is primarily a readability/maintainability refactor plus doc clarity.
