feat(messages): Implement "message read by" counter

This commit introduces the ability to see how many people have read an outgoing message in a group chat. A "views" count is now displayed in the message options dialog for relevant messages.

- **API & Data Layer:**
  - Added `getMessageReadPeers` to `MessagesService` and `MessagesRepository` to fetch users who have read a specific message.
  - Introduced `MessagesGetReadPeersResponse` to handle the API response.
  - A new URL constant `GET_MESSAGE_READ_PEERS` was added.

- **Domain Layer:**
  - A new `GetMessageReadPeersUseCase` is created to provide the view count to the ViewModel.
  - The use case is registered in the `DomainModule`.

- **ViewModel:**
  - `MessagesHistoryViewModel` now includes `loadMessageReadPeers` to asynchronously fetch and return the view count for a message.

- **UI (Compose):**
  - The `MessageOptionsDialog` now displays a "views" count for outgoing chat messages.
  - It uses a `LaunchedEffect` to call `loadMessageReadPeers` when the dialog is shown.
  - The `visibility` icon has been updated and its XML file renamed to `round_visibility_24px.xml` to follow a consistent naming convention.

- **Refactoring & Minor Fixes:**
  - Simplified several `derivedStateOf` usages to direct calculations or property delegates in `MessageBubble.kt` and `MessagesList.kt` for minor performance improvements.
  - Renamed `IncomingMessageBubble.kt` and `OutgoingMessageBubble.kt` to `MessageBubbleIncoming.kt` and `MessageBubbleOutgoing.kt` respectively for consistency.
  - Removed an unnecessary log statement in `MessagesList.kt`.
