Provider moved the INC CDC feed to a new bucket (tickets -> isptickets, new
per-bucket creds; same s3.rahamafresh.com endpoint, identical 32-col schema).
This is config + a one-time reseed, not a rewrite — the loader already drains
automations/inc/changes/ oldest->newest with a source_max_key watermark.
- default _BUCKET -> isptickets (TICKETS_BUCKET still overrides)
- add --reseed: ignore the stored watermark and drain every changes/ file once
(the old-bucket watermark may post-date the new bucket's first file). Crash-safe
via the existing per-file watermark-advance + archive loop.
- refresh stale "newest-file / full-snapshot-per-hour" docstring/comments to the
CDC reality; .env.example + README updated (new bucket + reseed runbook).
Verified live dry-run: 41/41 files drained (watermark None), alarm/sentinel
filter active, exit 0.

Rework import_tickets.py from the retired JSON `latest.json` model to the new
hourly full-snapshot CSV export. Strictly INC (CRQ out of scope).
- Ingest the newest automations/inc/<EAT-timestamp>.csv; skip-if-unchanged by
comparing S3 ETag to tickets.import_meta.metadata.source_etag.
- Upsert on ticket_id (PK; no dups, never delete -> closure history accrues).
No truncate. On success, move processed files to automations/inc/processed/.
- Clean at ingest: drop is_alarm=true + the "EXPORT STOPPED..." sentinel; drop
week_*, source_s3_*/source_snapshot_id, department/source_type; lowercase
region, uppercase raw_status; keep service_type + bucket.
- Force path-style S3 addressing; --inc-csv for local dev; --from-bucket for cron.
- Add migrations/02 (import_meta + freshness); refresh README/.env.example/docs.
