Refactor app defaults save logic and remove error handlers
Reworks the app defaults save/update logic in misc/build.func to support updating existing defaults with a diff and interactive menu, and adds robust var_* parsing and whitelisting. Removes legacy error and curl handler functions from misc/core.func, streamlining error handling and reducing code duplication.
