Introduce gamification and check-in support plus expanded transport/admin APIs. Added DDL for checkins, badges and user_badges. New repositories: badgeRepository, userBadgeRepository, checkinRepository. New routes: admin badge management, admin transport (lines/platforms/stations), public transport endpoints, user checkins and stations endpoints, and user badges on /me. Services updated: adminService (badge CRUD & user assignment), userService (checkins, badge queries), authService (hasAdminRights). Minor package.json name update. These changes implement database, repo, service and route wiring for badges, user_badins and checkin features and additional transport admin routes.
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).
