refactor: add docker/rename-databases.sh for in-place MS SQL cutover

Renames ScadaLink* databases + scadalink_app login on an existing running scadabridge-mssql container. For users preserving seeded test data through the rename. Fresh deployments use the already- updated infra/mssql/setup.sql directly.

+#!/usr/bin/env bash
+# docker/rename-databases.sh
+#
+# In-place rename of the MS SQL databases from ScadaLink* → ScadaBridge*.
+# Use this when you have an existing ScadaLink dev stack and want to preserve
+# the seeded test data through the product rename. If you're starting fresh,
+# just run `bash docker/deploy.sh` instead — infra/mssql/setup.sql now creates
+# the databases with their new names directly.
+#
+# The MS SQL container itself (renamed scadalink-mssql → scadabridge-mssql in
+# infra/docker-compose.yml) must already be running. If you also renamed the
+# container, do the container rename + volume remount before this script.
+#
+# Usage:
+#   bash docker/rename-databases.sh                 # primary databases only
+#   bash docker/rename-databases.sh --include-env2  # primary + env2 databases
+#
+# After running, restart the application containers so EF picks up the new
+# database names from the migrated connection strings:
+#   bash docker/teardown.sh && bash docker/deploy.sh
+#   bash docker-env2/teardown.sh && bash docker-env2/deploy.sh   # if env2
