Add parent journey(s) to Challenge/Opportunity notifications

[SimoneZaza]

Description

As a user I don't always know what context a notification comes from. Challenge/Opportunity titles are often only informative in context, eg Challenges such as "Coordination" and "Raising Awareness". I would like to see in the notification what Space (/Challenge) this CH/Oppis part of.

Acceptance criteria

• Below the action button, a breadcrumb-like thing showing Space title > Challenge title > Opportunity title, all clickable, no underline, in primary color
• The payload for journey type is expanded to include the displayName for each journey level
• Usage of the nameID / displayname for each level to create the breadcrumb
