Authorization must be implemented using token session stored in cookies

• [x] use @fastify/cookie, @fastify/session plugins
• [x] session options should be configurable using config module
• [x] implement auth service which should provide: signup, authorize logic
• [x] implement auth controller which should provide access to auth service and manage session
• [x] implement password hashing using node:crypto module
