Walkthrough

This update introduces platform-specific cURL code generation for API usage, splitting the API modal's cURL tab into Unix and PowerShell variants. It also streamlines authentication logic on the backend, adds dynamic UI configuration for export components, clarifies error messages, and bumps project and dependency versions. Several JSON starter project files receive whitespace formatting adjustments.

Suggestion is to leave top level as "cURL", then provide sub-tabs for platforms. Auto-detect platform to open appropriate tab.
