refactor(react-popover): inline dev-only warning at call site

- Remove nonInteractiveContentWarning constant from public API (constants.ts)
- Inline warning message directly in console.warn() call in usePopover.ts
- Removes logging noise from public API exports
- Update tests to use inlined warning message instead of constant reference
