Fix to users soft_delete

[lucasleandro1]

Context

• duplicate validations that ignored soft_delete

Solution

• validatable devise method overridden to consider soft_delete

Fix #327

[danielnottingham]

About the context: "duplicate validations that ignored soft_delete"

1. The implementation completely removes unique email validation.
   Problem: If the goal is to make validations consider soft delete, you shouldn't remove the validation, but adjust it.

2. Why remove unique email validation?
   validates :email, uniqueness: { case_sensitive: false }

Reported problem: Validations ignored soft delete.
3. Why not add better validation for this case? conditions: -> { where(deleted_at: nil) }

4. I don't understand this migration to remove the index and then add another.

• Remove unique email index
• Recreate the same unique index

5. Is this method really necessary? destroy_fully

I think we should do this at controller level, not at model level.

We only need to update to use realy_destroy here https://github.com/espoo-dev/med_system_backend/blob/main/app/controllers/api/v1/users_controller.rb#L14
