As a user, I should be presented with a notice that reveals what mode of AMP I’m using so I understand what each action does based on the current mode.

Without this notice, a given user may think actions take effect on their site, but when auto-sanitize mode is turned on (either by force for "Native" mode or optionally for "Paired" mode),

• AC1: Surface a given notice based on the mode (from the settings page) in each of the views where actions can occur.
• AC2: Propose copy (and perhaps a suggestion to turn on Auto Suppression) for Native, Paired (non-auto) and Paired (auto) modes. Also, in Paired Mode (non-auto) offer a dismissable notice to help the user turn this on to enable auto sanitization sitewide.

Notes:

• If a user is in Paired Mode with auto-sanitize or in Native AMP mode, each error is but a notice and does not affect the site.
• If a user is in Paired Mode without auto-sanitize, each action might affect which pages are served as AMP. A given user, by not taking action on errors, would prevent AMP from being served on those pages.
• If a user is in Classic Mode, they should know they won't get the index listings (nor the single listings) as the sanitizer does not run in this mode.
