Local storage is an untyped interface external to the frontend code
itself. The `data` field after `JSON.parse`'d from `raw_data` can be
further validated using `zod`'s schema `formDataSchema`.
The test case `server_upgrade_alert hide_duration_expired` in
`navbar_alerts.test.js` has a bug at `start_time`, which is fixed in
this commit. `start_time` is a mock value of `Date.now()` used in
`localstorage.ts`, which will concatenate with a number `expires`.
So `start_time` was supposed to be an integer value. Before fix, `new
Date(1620327447050)` returns a `Date` object which is wrongly
concatenated with `expires`.
Fixes#24997.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
