Improve the microcopy on the view password settings page

Hi again, thank you for your input here.

I created a branch to start these fixes.

• Remove "Please" word from the form (2 found)
• Change form labels
• Improve the field descriptions

These are the proposed changes so far:

I'd also update the validation message for the Form id(s) field to be:

The <em>Form id(s)</em> field should contain values separated by commas only. Spaces or new lines are not allowed.

I merged and closed this because there was no feedback against it. Thanks @rkoller for the ticket.

Automatically closed - issue fixed for 2 weeks with no activity.
