Match on AP intermediaries, retain them in Credit and write them into Supplier Collection

[paperboyo]

Co-authored by Claude Opus 4.6. Description written by a human, 48.

What does this change?

This is a followup to #4741. It:

• matches on …/AP credits, writing prefixes into Supplier Collection and retaining original Credit line
• removes redundant Invision-specific matcher
• removes outdated test that can’t happen now we have BylineCreditReorganiser (and other) cleaners

Worth noting that it will retain some credits we will want to clean more. Mostly, the ones mentioning Pool in all sorts of combinations, but also some other redundant or ugly things. Proper fix from here will clean them better (and remove redundant Description blobs too).

How can success be measured?

AP images from third-party intermediaries are recognised correctly
