migration(workflow-engine): Replace boolean deescalation comparisons

[sentry-junior]

Add a post-deployment data migration that replaces stored boolean true comparisons for issue-priority de-escalation conditions with the high-priority threshold (75). Other condition types and existing numeric thresholds are left unchanged.

Note that due to caches, we may still be using these for up to 4 hours after the migration, but considering how rare and already-broken these cases are, that's acceptable vs the complexity of invalidation.

Refs ISWF-3453 and ISWF-3455.

To be merged after #124304 so we know the door is closed to new violations.

generally lgtm, just a little nervous about the unindexed column with the issue from ~2 weeks ago.
