refactor(components): migrate forms from `vuelidate` and `vee-validate` to `tanstack/form`

[vuelidate](https://vuelidate-next.netlify.app/) is not maintained any more, replace it

- with ﻿[tanstack/form](https://tanstack.com/form/latest)﻿ (plus ﻿[zod](https://zod.dev/) maybe)
- or [vee-validate](https://vee-validate.logaretm.com/v4/)
