Description of problem:
When creating a template with 2 inputs with the same name, the error "uninitialized constant #<Class:0x000000000b894c38>::NonUniqueInputsError" appears and the operation fails. No traceback in production.log. Failure is expected but it should be handled better: the message should be more user friendly and preferably, the check should be handled before submitting the form.
Version-Release number of selected component (if applicable):
Reproduced on Sat 6.6 snap 22.
Steps to Reproduce:
1. Monitor -> Report Templates -> Create
2. Set name
3. Go to Inputs tab
4. Add input, name it "abc"
5. Add another input, name it "abc"
Error, operation failed

Using reproducer from OP, after submitting, I get:
Unable to save
ERF42-3514 [Foreman::Exception]: Duplicated inputs detected: ["abc"]
Using Hammer, I get (no change here):
Could not create the template input:
Name has already been taken
Adding different-named inputs works.
