Fase 1a: driver mongodb v3.7 (produccion es MongoDB 3.2)

Browse source 
El smoke-test contra prod revelo MongoDB 3.2.11 (EOL): el driver v6 exige >=4.2
y no conecta. Cambios:

- mongodb ^3.7.4 + @types/mongodb; db.ts con useUnifiedTopology, sin retryWrites
- sends.ts: deteccion de duplicate-key (11000) sin depender de MongoServerError
- poller.ts: FilterQuery en vez de Filter
- tests de integracion migrados de mongodb-memory-server a un fake en memoria
  (test/fake-repo.ts) porque no hay mongod 3.x ejecutable en hosts modernos;
  emula operadores ($ne/$in/$gte/$exists), $set/$unset e indice unico (11000)
- docs: legacy-behavior.md §0 (entorno MongoDB 3.2, sin change streams -> fase
  1b usara polling; recomendacion de upgrade de Mongo como fase propia)
