[GordiNoki]

Closes #705
Closes #318

When uploading BSP for map submission s3 pre-signed urls will be used now.

Checks

• I have included/updated tests where applicable (see Testing)
• I have ran nx run db:create-migration and committed the migration if I've made DB schema changes
• I have followed semantic commit messages e.g. feat: Add foo, chore: Update bar, etc...
• My branch has a clear history of changes that can be easy to follow when being reviewed commit-by-commit
• My branch is functionally complete; the only changes to be done will be those potentially requested in code review
• All changes requested in review have been fixuped into my original commits
