Upgrade: Rails 7.1 → 7.2 & Ruby 3.1.7 → 3.2.9

[kaysiz]

Purpose

https://github.com/datacite/product-backlog/issues/506

• Security & Maintenance: Rails 7.1 approaching end-of-life, Rails 7.2 provides latest security patches and bug fixes
• Performance Goals: Ruby 3.2.9 offers significant performance improvements (MJIT enhancements, better GC)
• Dependency Compatibility: Many gems require newer Rails versions for optimal compatibility

Approach

Incremental Migration Strategy

• Configuration Updates: Updated config.load_defaults from 7.1 to 7.2
• Compatibility Fixes: Addressed breaking changes one subsystem at a time:
  • JWT authentication system
  • Database testing infrastructure
  • GraphQL type system
  • Elasticsearch integration
  • Audit trail functionality

Testing & Validation

• Test-Driven Fixes: Fixed failing tests to understand exact compatibility issues
• Regression Prevention: Ensured each fix didn't break other functionality

Types of changes

• Bug fix (non-breaking change which fixes an issue)

• New feature (non-breaking change which adds functionality)

• Breaking change (fix or feature that would cause existing functionality to change)

Reviewer, please remember our guidelines:

• Be humble in the language and feedback you give, ask don't tell.
• Consider using positive language as opposed to neutral when offering feedback. This is to avoid the negative bias that can occur with neutral language appearing negative.
• Offer suggestions on how to improve code e.g. simplification or expanding clarity.
• Ensure you give reasons for the changes you are proposing.

@kaysiz Overall fantastic work.

We should test this with ruby 3.2
I see you updated the Dockerfile, but we should also update the version of Ruby used in the github action. Currently it is testing with version 3.1.6
