user-management

[usecymk]

Description

Adds a basic user management system: create users and change passwords, with users stored in Postgres. User management is optional and only enabled when DATABASE_URL is set.

Resolves Issue #16

Changes Made

• API: Postgres-backed user store (api/db/db.go): list users, create user (bcrypt), change password. Endpoints: GET/POST /api/users, PUT /api/users/:id/password. Enabled only when DATABASE_URL is set.
• Frontend: "Users" item in dashboard nav; Users page with user list, "Add user" form, and per-user "Change password" (inline).
• Deploy: Install script sets up Postgres (Docker) and /opt/altsuite/env when Docker is present so user management works out of the box. Update script ensures Postgres is running if present; uninstall stops the user-management Postgres container.
• Docs: README updated for user management (auto-setup and manual option).
• Tests: api/db/db_test.go for user DB operations; Go workflow updated with Postgres service and DATABASE_URL so these tests run in CI.

Testing

• Tested locally (API + frontend + Postgres)
• Added/updated unit tests (db package tests; Go workflow runs them with Postgres)
• All tests passing
