Aggregated rating and attribution (Pro)

When several sources are connected, Refresh Now collects each one and combines them:

• The overall average is weighted by each source's total review count (not by how many texts the API returned).
• The rating summary shows a chip per source with its own score and count.
• The attribution line becomes Reviews from Google, Trustpilot, … and links each source to its profile when the API provides one.

If one source fails (bad key, quota, outage) the others are still saved and the dashboard shows a warning naming the source. The failing source's reviews are simply missing from the cache until you fix it and refresh again.
