Fixes policy details page

[dbbaughe]

• Moves ISM templates out of the policy settings panel into it's own panel
• Fixes the edit button always going to edit as JSON, now it shows a modal and lets user choose.
• We were passing in error notification and trying to render as a channel id which crashes the page whenever there is an error notification, now we changed Channel ID -> Error Notification and have a link when it exists that opens up a JSON Modal w/ the error notification JSON
• Fixes a bunch of typescript errors
• Fixes states not actually being read-only on the policy details page by utilizing the passed in isReadOnly prop
• Creates a JSONModal to reuse for policy JSON and error notification JSON
