[WIP] Implement OTP versioning in DM and RoomChat

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

RoomChat'teki OTP versiyonu sistemini DM'e de implemente et. OTP v0 ve v1'i. Default olarak otp_v1 kullan DM'de. Ayrıca Room Chat'te X karakterden büyük anahtarlardaki mesajı şeyini DM'e de implemente et.

RoomChat'e bu OTP versiyon sistemini eklediğimiz commit'in patch dosyası: Buradaki işleyişi analiz et, tasklar oluştur, sonrasında o taskları uygula. Kısaca, versiyonlama eklenecek logic layer'a. Frontend'e gelişmiş ayarlar eklenecek ve otp sürümü seçme eklenecek.

Subject: [PATCH] Add OTP algorithm versioning and advanced settings

Introduces a modular OTP algorithm system with support for multiple versions (v0, v1), including a registry and type definitions. Adds advanced settings to room creation and join screens for selecting OTP encryption version. Updates RoomHistoryService, RoomListScreen, RoomChatScreen, enhancedWebSocketService, and roomOtpStore to track and use the selected OTP version per room, ensuring correct key transformation and encryption. Also adds UI for displaying and changing encryption type, and improves room management actions.
