Subject: [PATCH 1/2] feat: add support for sending messages with Ctrl+Enter

This commit modifies the `initInputContainer` function to add support for sending messages with Ctrl+Enter. If the user presses Ctrl+Enter, the message is sent without adding a new line. If the user presses Enter without Ctrl or Shift, a new line is added to the input field. The commit also removes unnecessary whitespace.

Subject: [PATCH 2/2] feat: Add auto-resizing functionality to message input

This commit adds the ability for the message input to automatically resize based on the number of lines of text entered. The input container will also resize accordingly. The function `autoResizeTextarea()` is called on input and sets the height of the message input and input container based on the number of lines of text entered. The default height is set to 16.
