kama-chat-server

Update a Kama Chat Vue frontend from the course SMS-auth flow to this repo's simplified backend contract: keep telephone+password login, simplify register to nickname+telephone+password, remove SMS login, and align routes/buttons/forms with `/login`, `/register`, and the disabled placeholder `/sendSmsCode` endpoint. Use this when editing Login/Register/SmsLogin pages, router guards, auth API wrappers, or navigation buttons.
