Pr05 Typescript Migration #18: Migrate client/modules/About & client/modules/Legal

[clairep94]

Picking off easy wins in the client/modules folder

• Was trying to record demos to show the steps to migrate a non-complex file for the Open Forum and did these
• Manually tested that all pages work after (as part of demos):

CHECKING.LEGAL.MIGRATION.mov

Changes:

• Migrate client/modules/About
• Migrate client/modules/Legal

Notes:
