Display site sync error status and error message

[olayway]

Currently it's not possible for the user to tell if the sync failed or succeeded. The UI only shows "Syncing..." or "Synced".
When the sync fails, the status in the UI just jumps back from "Syncing..." to "Success" and the only indicator that it failed is that the last sync date doesn't update.

Instead we could at least display the "❌ Failed" status. And ideally also display an error message.

Acceptance

• sync status and potential error message are communicated well in the UI

Shaping

Situation

Currently we only display two sync status information:

1. "Syncing..."/"Success"
2. Last synced timestamp

Appetite

0.5-1 day

Problem

When the site sync fails, the sync status shown in the UI is very misleading. It says that the site is "Synced", and the only indicator that it's actually not, is that the "Last synced" timestamp hasn't updated with the new date-time.

Solution

Option 1: Display error message on hover over "Failed status"

Option 2: Display error message in a separate "Logs" page

• actual error displayed in the tab

Although this second might be an overkill if we only want to display the last error message, and nothing if the sync was successful.

Rabbit-holes

No-goes

• Gathering and displaying historical logs Let's just display the only message that actually matters for the user who's trying to get their content up-to-date. Any other logs e.g. of any past syncs would be nice, but do not add real value for the user. Though might be cool to see past syncs that were e.g. auto-triggered.

@rufuspollock Let me know what you think. I'd personally go with the 1 option.
