Retire API v1 ingest URLs (`/api/raw-packet/`, legacy node paths)

[pskillen]

Summary

Meshtastic packet ingest v1 used unscoped URLs (POST /api/raw-packet/, /api/nodes/) that predate the current packets app layout. v2 uses observer-scoped routes:

• POST /api/packets/{node_id}/ingest/
• POST /api/packets/{node_id}/nodes/

OpenAPI now documents v2 paths and marks POST /raw-packet/ as deprecated (SP-01 #308). v1 is not registered in the current Django urlconf (Meshflow/urls.py → packets.urls only exposes {node_id}/ingest/ and {node_id}/nodes/).

Goal

Formally retire v1 on the API side and coordinate with meshflow-bot dropping STORAGE_API_VERSION=1 (see linked bot issue).

Scope (API)

• Confirm no production urlconf / reverse-proxy still depends on /api/raw-packet/ (or document explicit redirect shim if required during transition)
• Remove or gate any dead v1 view code if it still exists in the tree
• Update operator docs (docs/features/packet-ingestion/, deploy examples) to state v2-only
• After bot default is v2 and operators migrated: remove deprecated POST /raw-packet/ from openapi.yaml (or keep stub only if a compat redirect remains)

Out of scope

• URL prefix rename /api/packets/ → /api/meshtastic/ (meshcore rename SP-03+)
• MeshCore ingest (/api/meshcore/packets/ingest/)
