Rename the resolvePageUrl UI helper to resolvePageURL
We need to follow consistent naming rules when using acronyms. The casing of the acronym should follow the casing of the first letter. In other words:
- all lowercase if used in the first segment
- all uppercase if used in any other segment
Thus, the helper should be named resolvePageURL, not resolvePageUrl.
We'll need to align all other cases in the public API with this convention. File a separate ADR issue to document this decision.
