Say that only the owner deletes a project (#272)

The API now answers an administrator 403 when they delete somebody
else's project. The pages still said an administrator deletes every
project like their own.

- API: the DELETE row names the 403, and the paragraph on
  administrators says deleting stays with the owner.
- Accounts: the list of what an administrator may do, and the Delete
  row of the user management.
- Architecture: one line on what `seesAll` covers.
- Development: the e2e total, 1602 to 1603.
