Description of change

This PR displays EYB activity on the relevant company overview page.

• EYB leads are displayed as recent activity cards and show their value (high/low/unknown) in the summary.
• Investment projects that have been created from an EYB lead have an updated summary that displays 'from EYB Lead' at the end.

Test instructions

EYB leads:

• Add an EYB lead to your environment

• To populate your database with EYB Lead instances:

  • In Docker, go to the api container
  • Go to the 'Exec' tab
  • Run the following commands

python manage.py shell
from datahub.investment_lead.test.factories import EYBLeadFactory
EYBLeadFactory.create_batch(1)

• Ensure the EYB Lead is linked to a company
• Visit the company overview page for that company
• A card displaying the EYB lead should be displayed under 'Recent activity'
• The card should have the 'EYB' tag
• In Django Admin update the 'Is high value' field to yes/no/unknown and check that the EYB activity card summary updates accordingly ('yes' = 'A high-value', 'no' = 'A low-value', 'unknown' = 'An unknown-value')

Linked investment projects:

• Visit the details page for your EYB Lead
• Click on the 'Add investment project' button
• Complete the process of creating an investment project. This project will be linked to your EYB lead
• Return to the company overview page
• A card displaying the investment project should be displayed under 'Recent activity'
• Check that the end of the summary text includes 'from EYB lead'
• Any investment projects not linked to an EYB lead should not display this additional text
