Remove old rules we don't actually need still

Full category (10/10 codes are all default in ruff 0.16). Of 54
hits, 46 were in test fixture code constructing naive datetimes for
comparison/input purposes only - added DTZ to the existing
per-file-ignores for */tests/*.py alongside E501/SIM117.

The 8 production hits:
- documents/consumer.py, documents/views.py (index_last_modified):
  suppressed with noqa - timezone.make_aware() requires a naive
  datetime, so wrapping fromtimestamp() in tz= would break it
- documents/double_sided.py (x2): switched to
  datetime.now(tz=UTC).timestamp() - behavior-identical since
  .timestamp() returns the same epoch value regardless of the
  attached tz, but now explicit
- documents/views.py (x2, upload temp file mtime): suppressed with
  noqa - mktime() requires a local time tuple, so an aware/UTC now()
  would introduce a timezone-offset bug
- documents/workflows/ai.py (AI suggested date parsing): suppressed
  with noqa - only .date() is used, time/tz is discarded
- paperless_mail/mail.py (IMAP fetch date filter): switched
  date.today() to timezone.localdate(), which respects
  settings.TIME_ZONE instead of the system clock - a real
  correctness improvement when they differ
- paperless_mail/views.py (placeholder name string): switched
  datetime.datetime.now() to timezone.now(), matching the app's
  existing aware-datetime convention
