feat: add placeholder terms of use page

Had some struggles with pre-commit locally getting:

[error] No matching files.

Prettier in the pre-commit is a different version that in package.json. There doesn't appear to be v3 versions after v3.1.0. And the repo is now marked as:

archived

prettier made some changes that breaks plugins entirely

Also, is the exclude in .pre-commit-config.yaml not telling it to ignore all .ts(x) files anyway?

Very odd. I ran npm run prettier-fix anyway so should be good, and Gitlab CI running it seems to have worked so may be just my setup.

Closes #31 (closed)
