feat: E2EE messages mentions

[hugocostadev]

Proposed changes (including videos or screenshots)

In Rocket.Chat, while end-to-end encryption secures user messages in private rooms, it currently does not support the functionality to mention specific users within these encrypted conversations. This limitation reduces the usability and interactivity of the chat, as users cannot directly alert or reference other participants. Enabling mentions in encrypted rooms will enhance communication efficiency and user engagement without compromising the security of the encryption.

Acceptance criteria (DoD)

• Functionality Implementation: Users should be able to mention other users, teams, and @ALL and @here in end-to-end encrypted rooms using the '@' symbol followed by the username, exactly the same functionality in non-encrypted rooms.
• Autocomplete Feature: As a user types a mention, an autocomplete feature should suggest possible usernames based on the current participants in the room, exactly the same functionality in non-encrypted rooms.
• Notification Handling: Users who are mentioned should receive notifications if they have notifications enabled, exactly the same functionality in non-encrypted rooms.
• Security Compliance: The implementation of mentions must not compromise the encryption integrity of the message, but it’s not required the mention to be end-to-end encrypted.
• Performance Impact: Ensure that the introduction of mentions does not significantly impact the performance and responsiveness of the chat system.
• User Experience: The user interface for mentions in encrypted rooms should be seamless and intuitive, without requiring additional steps or complications for the user.
• Accessibility and Compatibility: Ensure that mentions are accessible and function consistently across all supported devices and platforms.
• Create a new setting
