Update test passwords from 'password123' to 'Password123!' to meet security requirements (uppercase, lowercase, digit, special char). Fix migrations test to match actual habit_entries schema (removed non-existent deleted_at column).
- Create test server setup with in-memory SQLite - Add auth flow tests (register, login, validation) - Add habit CRUD tests (create, read, update, archive) - Add habit entries tests (mark, unmark, get entries) - Test authorization and cross-user access control
