Real-time collaboration ⚡️

[FelixMalfait]

Right now we don't have any websocket in place to sync data in real-time but this is definitely something we will need in the future.

Example features we could build:

• Refresh people/companies/objects lists as they are updated
• Show with a color border when someone is editing a field on a record
• Update comments threads panel as comments are sent
• Update inbox page as inbox notifications are received (later / inbox page isn't built yet as I'm writing this)
• View who is viewing the same page (later / record show page isn't built yet as I'm writing this)
