[satyam-equinor]

New design has been done with the following changes.

Acceptance criteria

• User lands on "My Processes" by default when opening Flyt.
• The "Create new" button has been modified to improve visibility, and align with EDS (Equinor Design System).
• The title on the process cards has been increased to improve readibility and navigation.
• For duplicates, "Duplicate of X" is set as a subtitle.
• The"last modified"-text size has been reduced to strenghten the visual hierarchy and increase emphasis on process titles.
