smoke: REST API regression harness + baseline snapshots (Meteor 1.6.1.1)

Adds a standalone Node smoke test (smoke/) that exercises every REST endpoint
consumed by the Flutter app against a seeded local dev server and compares
responses to committed snapshots. This is the safety net for the Meteor upgrade:
it must stay byte-identical after every escala.

- smoke/seed.js: deterministic Mongo seed (fixed ObjectIds, geo indexes)
- smoke/run.js: calls endpoints, normalizes volatile fields, diffs snapshots
- smoke/smoke.sh: seed + run wrapper
- smoke/snapshots/: baseline captured on Meteor 1.6.1.1
- IPGeocoder.js: degrade gracefully when MaxMind DB absent (dev boot)
- settings-development.json: dev-only internalApiToken to enable the REST API
- .meteorignore: exclude smoke/ from the Meteor server build
