Integrates file sharing into the chat interface so uploaded files appear as messages in the chat timeline alongside text
messages.
Changes:
- Created FileMessage component for inline file display in chat
- Extracted FileItem component for reusable file UI across chat and file sharing tab
- Show "A file was deleted" placeholder instead of removing message when file deleted
- Hide message menu (3-dot) when no actions are available for file messages
- Add button backgrounds in chat context to hide text on hover
- Fix timing: local participant only sees file message after upload completes (progress: 100%)
Technical implementation:
- Added fileMetadata field to IMessage interface
- Added isDeleted flag to IFileMetadata for soft-delete state
- Middleware dispatches addMessage when files uploaded (ADD_FILE action)
- Middleware uses editMessage when files deleted to preserve chat history
- Minimal state retention (only isDeleted flag) for deleted files
This provides a unified messaging experience where file sharing is part of the conversation flow.
Before the chat message context menu was appearing on the left if the private chat message was disabled. The fix makes the context menu appear on the left only for messages from the local partcipant which are the only messages rendered to the right (therefore the context menu have to appear on the left side). For all other messages the context menu should appear on the right side because the message is positioned on the left side.
