Add CreatedBy as new standard field

[Bonapara]

Current Behavior

Currently, there is no way to determine the source of a record's creation. For instance, if several people are using a workspace linked to their email addresses, determining who created a company can be challenging.

Desired Behavior

Introduce a Created by field in every object, comprised of:

• Creation Source
• Creator Name

Creation Source

Initial sources include: Email, Calendar, API, Import, Manual.

Future additions may encompass Integrations/Third-party apps and Workflows. Each source should be represented by an icon preceding the Creator name.

Creator Name

• For manually added records: User name
• For records added in user name: User name
• For records added via API: API name

Aim to attribute the person's name as creator whenever feasible.

Technical input

This should be a composite field that includes:

• An enum for the Creation Source
• A foreign to workspaceMember for Creator name
• A text field that will be used as fallback if there is not foreign key to workspace (e.g. for api key or maybe we can backfill this in case a workspace member is deleted)
