Railbase core v0.5.28

App-user password reset with full 10-language i18n, plus internal cleanup and release-tooling hardening.

Highlights

• Password reset for app users — the site sign-in now has a complete forgot-password / reset-password flow, localized across all 10 supported languages.

Fixes & internals

• Removed dead Go code and unused internal packages flagged by staticcheck U1000, and cleaned up the var _ = import keep-alive shims that were masking them (no behavior change).
• Hardened the one-command release pipeline (ship.sh).
