Improved Error Handling

[faizanraso]

When creating a new bucket in the Storage section of a project, I kept trying to name the bucket "TestBucket", but I didn't notice the note that said capital values can't be used. When the error toast appeared, it only said invalid name. I think it may be helpful to show either an improved error message that lets you know what was wrong in the bucket name you selected, or live error handling when you're typing in the name (i.e. change the input border to red when you enter an invalid character").

Would love to create a PR for this if someone can direct me in how I should approach this problem.
