feat(email): track deliverability

[dargmuesli]

This pull request introduces a new table to track email addresses with deliverability issues (such as bounces, complaints, and unsubscribes) in the vibetype_private schema. The implementation includes a new enum type for email address status, associated constraints, metadata triggers, and relevant schema updates for migration and verification. The changes also include the necessary revert and verification scripts, as well as updates to the test schema fixtures.

Details

• Threshold for regression warnings: >15% and ≥1ms absolute change
• Deltas in parentheses indicate that the absolute change is below the minimum threshold
• Each measurement discards the first (cold-cache) execution, then reports the median of all subsequent runs within a 5-second time budget
• Timings use clock_timestamp() with JIT compilation and synchronized sequential scans disabled
• Data: 1000 accounts, 100 events, 1000 contacts, ~1000 guests, 200 attendances
• Runner: GitHub Actions (timings may vary ±10% between runs)
• Workflow run
