[Task]: Log field-level details for EDIT_PROPERTIES (action 2) and CHANGE_MEDIA (action 39)

[mixedpuppy]

Description

These events do not expose what the change was, only that a change occurred. A recent addon that I looked into was more difficult due to this.

When a developer edits addon properties, EDIT_PROPERTIES (action 2) and CHANGE_MEDIA (action 39) log entries record only the addon reference in arguments - e.g., [{"addons.addon": ###}]. There is no record of which fields were changed or what the old/new values were.

Acceptance Criteria

• EDIT_PROPERTIES and CHANGE_MEDIA are extended to include what changed, value may not make sense to include. Alternately fire 208 for more of the changes.
