Correct version to 1.2.1: v1.2.0 was already tagged for load balancing

The load-balancing feature (merged in #172/#173) was tagged v1.2.0 on
GitHub, but nodejs/package.json and CHANGELOG.md were never bumped for
it. Backfill a 1.2.0 CHANGELOG entry and bump this release to 1.2.1
instead of 1.1.18, so package.json/CHANGELOG stay ahead of the highest
existing tag rather than behind it.

 ### Fixed
 - The bootstrap anti-lockout admin account was always created as `proxyadmin2` regardless of `conf.auth.adminUsers`, while `migrations/permission_bootstrap.js` grants the global-admin permission to `conf.auth.adminUsers[0]`. If an operator customized `adminUsers` away from the default, the bootstrapped account and the permissioned account were two different (non-matching) usernames, so the anti-lockout account ended up with no admin access. `models/user_redis.js` now derives the bootstrap username from `conf.auth.adminUsers[0]` (falling back to `proxyadmin2`), matching `permission_bootstrap.js`.

 ### Changed
 - Refreshed all README screenshots (hosts, per-host SSO auth, per-host basic auth) against the current UI, and added a new load-balancing screenshot for the multi-target feature.

+### Added
+- Multi-target load balancing: hosts can now specify additional backend targets (`IP:port`, one per line) alongside the primary target; the proxy distributes requests across all of them round-robin via `lua-resty-balancer`. Fixes #47.
