feat: extract file text on every attach path and backfill on reindex

- inline and signed uploads queue the text job in their transaction
- the admin form queues it in the save transaction
- detach resyncs the material (its text row goes by cascade)
- bm:materials-reindex backfills missing PDF texts before each sync
