bvandeusen 6959e1220c Revert "db: collapse alembic 0001..0087 into one baseline"
This reverts 2529b51. Not a retreat — a reordering, on the operator's
call, and the better sequence.

The squash's acceptance test (run 4971) found ~130 places where the ORM
models do not describe the deployed schema (#3275), including a
unique=True the database never had and two UNIQUE indexes that exist
only in migrations. Collapsing now would have baked all of that into the
one file a public installer starts from.

So: fix the drift first as ordinary migrations on the intact chain, let
the operator deploy so their database moves to the corrected head, and
only then collapse. The baseline is then generated from reconciled
models and reproduces a schema worth reproducing.

Nothing is lost by reverting. The baseline was never deployed, and
regenerating it after the fixes is strictly better than patching this
copy — it will come out of autogenerate correct rather than needing the
same hand-finishing twice.

"""image_record: source_url + source_filehash (inline-image localization)
#830 Phase 2. To render a post body faithfully we serve LOCAL copies of inline
images instead of hotlinking the public CDN. The join key between a body
`<img src=CDN>` and the local file is the CDN's 32-hex filehash (the same
identity extract_media dedups by). Persist it (indexed) plus the full source
URL for provenance/debugging. Both NULL for filesystem-imported / pre-existing
rows — those fall back to hotlinking until re-downloaded.
