Add linkage to information about IFRC event leveling (i.e. Crisis Categorisation)

Is your feature request related to a problem? Please describe.
Feature request to add contextual information to the disaster categorization field.

Describe the solution you'd like
I've spoken to users that are confused about the "Disaster Categorization" field under Emergency Overview on emergency pages. I think either converting that label to a link, or having help text icon (accessible via hover) that provides access to guidance on the definitions and implications of each color code would be helpful.

Additional context

These two documents capture the information I'd like to have accessible:
IFRC Global Tools Review Final Report.pdf
IFRC Leading Emergency Assessment and Planning.pdf

On the “IFRC Global Tools Review Final Report English” doc, check page 7. On “IFRC LEAP approach Sept. 2018”, check page 33.

Should there be any restrictions around viewing or updating information related to this feature
No
