Fix circular imports causing React dispatcher null error

Extract shared utilities (constants, helpers, components) from App.jsx
into src/utils/bibleUtils.jsx so page components can import from there
instead of from App.jsx. This breaks the App.jsx <-> pages circular
dependency that was triggering vite:import-analysis warnings and causing
the React hook dispatcher to be null at runtime.
