Hook data sync into Rails db setup tasks

[bdurand]

Added

• The data synchronization task is now automatically attached to several Rails tasks: db:seed, db:seed:replant, db:prepare, db:test:prepare, db:fixtures:load. Support tables will be synced after running any of these tasks. This can be disabled by setting config.support_table.auto_sync = false in the Rails application configuration.

Pull request overview

This PR enhances the support_table_data gem to automatically synchronize support table data when running common Rails database tasks. The main change introduces automatic task hooks that trigger the data synchronization after tasks like db:seed, db:prepare, and db:test:prepare, with a configuration option to disable this behavior.

Key changes:

• Automatic synchronization task hooks for common Rails database tasks (configurable via config.support_table.auto_sync)
• Refactored support_table_key_attribute implementation to use a private backing attribute with explicit default behavior
• New ValidationError class that provides better context when validation failures occur during data synchronization
