Ruff lint surfaced 23 violations across three rules; all addressed:
UP017 (Use datetime.UTC alias):
Replaced 13 sites of datetime.now(timezone.utc) with datetime.now(UTC),
also adjusted from-imports accordingly. UTC is a Python 3.11+ alias for
timezone.utc that ruff's pyupgrade rules prefer.
UP042 (StrEnum):
Replaced `class TagKind(str, Enum)` and `class SkipReason(str, Enum)`
with `class Foo(StrEnum)`. StrEnum was added in Python 3.11 stdlib and
is the modern idiom. Behavior is equivalent for our usage (the .value
attribute, str(member) semantics).
I001 (Import sorting):
Added `known-first-party = ["backend"]` to ruff.toml's [lint.isort] so
ruff groups `backend.*` imports correctly. Without it, ruff treated
them as third-party and demanded a different grouping. The existing
import order is stdlib → third-party → first-party → local relative,
which ruff now accepts.

recover_interrupted_tasks runs every 5 minutes, finds ImportTask rows
stuck in 'processing' for >30 minutes (well above any legitimate import
duration), and re-queues them. cleanup_old_tasks runs daily and deletes
finished tasks older than 7 days so the task table stays an operational
view rather than an archive.
Both thresholds match ImageRepo's precedent. The 30-min stuck threshold
is documented inline so a future reader can adjust it intentionally
rather than mistaking it for a 'magic number'.
