chore(release): public-release readiness fixes for 1.1.16

- Fix MIT LICENSE copyright placeholder
- Remove private flag and correct GitHub repository URL in package.json
- Bump version to 1.1.16
- Genericize committed config defaults (example.com/localhost)
- Harden global error handler against information leakage
- Generate random initial password for proxyadmin2 bootstrap account
- Correct docs to describe CONF_SECRETS instead of symlink behavior
