The nightly database backup (and "Run DB backup now") now sends pg_dump's
output straight to the off-site bucket as a multipart upload, with no copy
staged on this server. The object is named database/fabledcurator-<UTC
time>.dump and appears only once pg_dump has exited cleanly and every part
has landed; a failed dump aborts the upload and records pg_dump's last line.
Without a destination, dumps are written to /images/_backups as before.
- backup_s3: Upload (start / add part / complete / abort), with a busy or
silent bucket rested and asked again (15 s, 60 s, Retry-After obeyed), and
a Pacer that holds uploads to the new bandwidth limit.
- Settings: "Upload limit (Mbit/s)" on the destination card, 200 by default,
0 for none (migration 0120).
- pg_dump runs under nice (and ionice where installed), locally too.
- Backups card says where dumps go; the runs table gains "Saved to" and
shows a failed run's error. Off-site rows have no restore/tag/delete here:
restoring from the bucket is a later step (#6880).
Task #6878, milestone 586.

Settings → Maintenance → Storage gains "Off-site backup destination": the
address (with its port), bucket, region, access key and secret key of an S3
bucket such as Fabled Archives. The secret key is sealed with the credential
key, never returned by the API, and kept when the field is left blank. Test
destination lists the bucket with the fields as typed and writes nothing, and
names the cause when it fails ("nothing is listening there (check the port)",
"the secret key is wrong", "answered, but not as S3").
services/backup_s3 is a standard-library SigV4 client (put, get, paged list)
ported from Grimoire's; it is held to AWS's published signing examples and
exercised against a local HTTP server. Migration 0118 adds the columns; no
destination is set up until someone saves one.

The `select(ImportSettings).where(id == 1)).scalar_one()` singleton load was
repeated 15× across services, API, and 5 task modules. Added async load() +
sync load_sync() classmethods on the model and migrated all 15 full-row sites
(callers already imported ImportSettings, so no new imports; dropped download's
now-orphaned select import). Left maintenance.py's deliberate column-select
(import_scan_path only) as-is.
Rest of the service layer was already adequately DRY — the Record/to_dict
pattern is only 2 instances and the savepoint find-or-create recovery is
correctly per-entity, so neither was forced into a shared abstraction.

8 blueprints each defined an identical _bad() (two variants: with/without
detail). Extracted error_response() into api/_responses.py; each blueprint
now imports it `as _bad` so call sites are unchanged. The detail-aware
canonical subsumes both variants. Left settings.py's distinct _bad_int and
the inline jsonify error sites (not duplicated helpers).
