fix: bulk add columns

[achettyiitr]

Description

• Since we are now handling errors during Polling (earlier we used to mark it as aborted instead of marking it as failed), We can call AddColumns with all the necessary columns.
  • In case some columns already exist (maybe another instead added them), we will get an error and will mark these jobs as a failure. They will be picked up again.

Linear Ticket

• Resolves WAR-115

Security

• The code changed/added as part of this pull request won't create any security issues with how the software is being used.
