Fix a number of typescript issues (#32308)
- Prefer
[window.location.assign](https://developer.mozilla.org/en-US/docs/Web/API/Location/assign)
over assigning to
[window.location](https://developer.mozilla.org/en-US/docs/Web/API/Window/location)
which typescript does not like. This works in all browsers including
PaleMoon.
- Fix all typescript issues in `web_src/js/webcomponents`, no behaviour
changes.
- ~~Workaround bug in `@typescript-eslint/no-unnecessary-type-assertion`
rule.~~
- Omit vendored file from type checks.
- `tsc` error count is reduce by 53 with these changes.

// if there is an "Invalid Date" error, there must be something wrong in code and should be fixed.
// TODO: there is a root problem in backend code: the date "YYYY-MM-DD" is passed to backend without timezone (eg: deadline),
// then backend parses it in server's timezone and stores the parsed timestamp into database.
// If the user's timezone is different from the server's, the date might be displayed in the wrong day.
