Adrian/nullify certain fields

[adrianviquez]

Adding certain fields to be nulled as they create fk dependencies for data not worth exporting. Also adds chunking to prevent transaction incorrectness when exporting

Legal Boilerplate

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. In 2022 this entity acquired Codecov and as result Sentry is going to need some rights from me in order to utilize my contributions in this PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.

Note

Optimizes and hardens owner data export and archive collection.

• Adds BATCH_SIZE chunking to all queryset .iterator() calls in archive_collector.py and sql_generator.py to process exports/copies in controlled batches
• Expands NULLIFIED_FIELDS to avoid FK/sensitive data: adds Owner.bot, OwnerProfile.default_org, Repository.fork/bot, and nullifies author on core.Commit and core.Pull
• Includes reports.RepositoryFlag in FULL_EXPORT_MODELS for always-on export
• Minor: wires BATCH_SIZE import where needed and uses it in UPSERT generation
