refactor!: make addrkit a multi-city address normalizer

- remove the events/outages module, ArcGIS adapter, portal config and event statuses
- add a configurable city dictionary/parser and make City part of StreetKey
- seed: read city/city_name, namespace IDs by city, keep structures distinct
- fix reliability: schema v2 with fail-closed load, deterministic ordering,
  input limits, config validation, atomic DB publish, LLM response caps
- add read-only shadow mode comparing the old ES path with addrkit
- breaking: registry.db must be re-seeded; config has no portal section
