tyler c3a6c53096 fix(sftp): case-insensitive inbound regex, skip _warn.txt, add targeted pull
Three changes that unblock the daily inbound pull from Gainwell's
FromHPE MFT path:

1. INBOUND_RE now accepts both 'TP' and 'tp' prefixes via inline
   (?i:TP) scoping — case-folding the whole pattern would let
   lowercase '837p' / tracking IDs through, which is invalid HCPF.
   The rest of the pattern is still case-sensitive.

2. _list_inbound_paramiko skips *_warn.txt entries. Gainwell's MFT
   drops ~583 advisory text-format notes in the same inbound dir;
   they come first alphabetically and were padding every poll with
   ~80 min of pointless downloads.

3. New SftpClient.list_inbound_names() + download_inbound() pair
   gives a metadata-only listing and on-demand fetch. The
   scheduler's existing full-listing path still works (now without
   the warn padding); the new path is what the new
   /api/admin/scheduler/pull-inbound endpoint and the
   'cyclone pull-inbound' CLI use to fast-target a date range
   without paying the cost of a full ~6000-file download.

Scheduler.process_inbound_files() runs the same per-file pipeline
as a regular tick on the pre-fetched list, so dedup via
processed_inbound_files still applies.

Tests added in test_filenames.py (lowercase + mixed-case cases),
test_sftp_paramiko.py (warn skip + no-download listing), and
test_scheduler.py (process_inbound_files idempotency).

With this, the daily 385-file pull for 20260624 completes in
seconds via 'docker exec cyclone-backend-1 python -m cyclone
pull-inbound --date 20260624 --block dzinesco' (or the equivalent
POST to /api/admin/scheduler/pull-inbound?date=20260624).

"""SP16 — Inbound MFT polling scheduler tests.
We test the Scheduler class with a fake ``SftpClient`` factory that
returns files we drop on disk (the SFTP stub already does this; we
just need to control which files appear between ticks). The handlers
themselves (999/835/277CA/TA1) are exercised through real parsers
using the fixtures in ``tests/fixtures/``.
