Add more inputs

I only implemented a few, just enough to test the core features. We need more specialized inputs:

- [ ] DateInput
- [ ] BooleanInput
- [ ] PasswordInput
- more ?

We can try to implement those from react-admin: https://marmelab.com/react-admin/Inputs.html

Start by reviewing the existing input implementations in this repository, then compare the requested DateInput, BooleanInput, and PasswordInput with the react-admin Inputs documentation linked in the issue. Done means those three inputs are implemented and the checklist is updated; the issue leaves any additional inputs open-ended.
