Add /messages/{message_id}/emoji endpoint to toggle, add, remove message emojis

Emoji protocol:

class EmojiCode(str, enum.Enum):
    thumbs_up = "+1"  # 👍
    thumbs_down = "-1"  # 👎
    red_flag = "red_flag"  # 🚩
    hundred = "100"  # 💯
    rofl = "rofl"  # 🤣"
    heart_eyes = "heart_eyes"  # 😍
    disappointed = "disappointed"  # 😞
    poop = "poop"  # 💩
    skull = "skull"  # 💀


class EmojiOp(str, enum.Enum):
    togggle = "toggle"
    add = "add"
    remove = "remove"


class MessageEmojiRequest(BaseModel):
    user: User
    op: EmojiOp = EmojiOp.togggle
    emoji: EmojiCode

JSON messages returned by the server /messages or /messages/cursor now have a emojis field with counts of the emojis (null by default).

Example:

{
  "id": "aa77f446-6a19-47cf-a20b-ee394b07c745",
  "frontend_message_id": "8080",
  "text": "world hello world foo foo hello world hello hello world",
  "lang": "en",
  "is_assistant": false,
  "parent_id": "c53581a6-ef17-4c69-a971-391c169f3366",
  "created_date": "2023-01-24T19:14:18.320648+00:00",
  "emojis": {
    "+1": 1
  }
}
