[lib] Update id constants

Summary:
ENG-4595
Not all ids were converted

Test Plan:

• for bots.js -> added a console.log in keyserver and web code and checked that only web had a prefix
• for comm-staff-community (I replaced 311733 with id of one of communities on my dev env for testing)
  • checked id: '311733', sent an image on web, confirmed that there is no "encryptionKey" in extra column in uploads
  • checked id: process.env['KEYSERVER'] ? '311733' : '256|311733', sent an image on web, confirmed that there is "encryptionKey"
• Searched for id: ', id = ', '1, '2 etc. (case insensitive) and checked if there are any other constants
• Checked files in facts/ for any id constants
