New document detail section

[maxjmohr]

Description

This PR contains an entirely new document detail section!

There are lots of changes:

• Move chat to a new section (left 40% of window size) Display last 5 lines of chat directly in the document overview #392
• New event pipeline! [Feature]: Create stream instead of chat and make it more prominent #234 For changes on documents, trigger events that are then also shown in Chats & Activities. The events are also stored in IPFS, so we leverage IPFS as an event hub! Each event is stored in this schema:

export interface RecordEventInput {
  eventType: EventType;
  eventAction: EventAction;
  objectId: string;
  workspaceOrigin: string;
  objectName?: string;
  docId?: string;
  versionCid?: string;
  version?: string;
  actorType?: EventActorType;
  actorNodeId?: string;
  actorUserId?: string;
  /** Override timestamp (ISO 8601). Defaults to now. */
  timestamp?: string;
}

• Automatically refresh the Chat & Activities section in the frontend through a minimal event bus, where notifyDocumentActivity adds an activity notification and components can subscribe via useDocumentActivitySubscription!
• Detect and display chat messages differently if they were created by the logged-in user
• Update previews for pdf (scroll instead of click through pages), docx and editable files.
• When clicking on a document, display the latest Chat & Activities (so by default scrolled to the bottom)
• Ability to edit chat messages [Feature]: Edit document messages #399
• Ability to like messages: likes are stored as new files in IPFS, which are then joined with chat messages with a new chatId per message:

export interface ChatLikeMeta {
  type: "chatLike";
  chatId: string;
  timestamp: string;
  creatorNodeId: string;
  creatorUserId: string;
  creatorName?: string;
}

• TBD: Ability to @ other users (perhaps we need a notification center for this?) [Feature]: In Chat, the option to "at"-a username and notification #226
