Improve Form Validation handling

[pmbanugo]

The forms currently only have basic client-side validation. The application should also do server-side validation, so that only valid data will be saved. It should ensure that:

• required fields are submitted
• the schedule value is properly checked based on the schedule type (e.g. cron expression or interval).
• clear messaging for form validation errors.

This could be implemented in a simplistic way using epicweb-dev/invariant. An alternative is to use Conform and Valibot. The following guides by Kent Dodds shows how to use it in Remix.

• Trellix Form Validation (video)
• Accessible, Typesafe, Progressively Enhanced Modern Web Forms
• Use Zod for All Form Validation - you can seee how he uses zod here and can replace it using Valibot during implementation.

Side note: perhaps root/apex domains like google.com should not be allowed because it's a waste of resource if they keep running and are not useful to the end user.

@pmbanugo i will take that

Just FYI, I’d like prefer if you used Valibot instead of Zod.
