Creating New Chatrooms without chat functionality yet.

[JRB958]

Related to #365
This PR introduces creating a chat feature with the following functionalities:

• Chat List View
• Implemented a chat list that displays all existing chat rooms (individual and group).
• Each chat card shows:
  • The chat title : group name for group chat or individual's name
  • The most recent message
  • The timestamp of the last message
• Starting a New Chat with an existing friend
  • From a friend's profile: Tapping the "Message" button opens or creates a one-on-one chat room.
  • From the chat tab ("+" button):
    • Selecting one user creates a new one-on-one chat.
    • Selecting multiple users prompts for a group name to create a group chat.
• Chat Room Screen
  • Integrated react-native-gifted-chat to render the chat interface (configuration to follow in future PRs).
  • The header displays:
  • Chat title (either the friend's name or the group name)
  • An info section:
    • Displays participants (if it's a group chat)
    • Options to leave or delete the chat (based on user permissions)

NOTES BEFORE REVIEW:

• you will get an error concerning the react-native-keyboard-controller library which is native and doesn't work with Expo Go so please ignore this error as it is not yet used in the implementation of the chat.
• sending messages is not yet implemented and will be in a future PR. this only regarding the routing and the creation of chatrooms (group and individuals)

Test steps:

to start a chat from the user profile with an individual

• login
• go to your friends list
• click on "Message"
• route to the chat with the user's title
• the title of the chat for the other user will be yours

to start a chat from the chat tab

• login
• go to chat tab
• click on the +
• select user(s)
• add group title if applicable
• create chat and route to it

creators of a chatroom can delete it*
members can leave it.*
