Add bans, user cache, auth routes & token changes

Introduce user bans and caching, extend schemas, and add auth/user endpoints. Adds bans DDL and banRepo plus adminService to manage bans; introduces modules/cache for in-memory user caching used by authService and userService. Updates users and credentials DDLs (role, isDisabled, shouldReset). Changes tokensService to include role in access tokens and store refresh tokens as SHA-256 hashes. Updates repos (credentials create RETURNING, usersRepo.updateProfile positional params), enhances authService with isLogged/isNotLogged middleware, ban checks, and refreshed token flow. Adds auth routes (login, logout, refresh, register) and user routes (/me).
