chore (SW-834): Upgrade to Next 15
* wip: apply codemod and upgrade swc plugin
* wip: design-system to react 19, fix issues from async (search)params
* wip: fix remaining issues from codemod
serverClient is now async because context use headers()
getLang is now async because it uses headers()
* Minor cleanup
* Inline react-material-symbols package
Package is seemingly not maintained any more and doesn't support
React 19. This copies the package source into `design-system`,
makes the necessary changes for 19 and export it for others to use.
* Fix missing awaits
* Disable modal exit animations
Enabling modal exit animations via isExiting prop is causing
modals to be rendered in "hidden" state and never unmount.
Seems to be an issue with react-aria-components,
see https://github.com/adobe/react-spectrum/issues/7563.
Can probably be fixed by rewriting to a solution similar to
https://react-spectrum.adobe.com/react-aria/examples/framer-modal-sheet.html
* Remove unstable cache implementation and use in memory cache locally
* Fix ref type in SelectFilter
* Use cloneElement to add key prop to element
