Fix migration: Update ALL adapter_config rows, not just mock

[EmmaLouise2018]

Problem

The deployment is failing with:

column "mock_manual_approval_required" of relation "adapter_config" contains null values
[SQL: ALTER TABLE adapter_config ALTER COLUMN mock_manual_approval_required SET NOT NULL]

Root Cause

Migration e38f2f6f395a only updated rows WHERE adapter_type = 'mock':

UPDATE adapter_config SET mock_manual_approval_required = false WHERE adapter_type = 'mock'

But then set NOT NULL constraint on the entire column, leaving NULL values for non-mock adapters (GAM, Kevel, etc.).

Fix

Update ALL existing rows before setting NOT NULL:

UPDATE adapter_config SET mock_manual_approval_required = false

Migration Steps

The migration correctly follows the pattern:

1. Add column as nullable ✅
2. Set values for ALL rows ✅ (fixed)
3. Make column NOT NULL ✅

This allows the migration to succeed for tenants with any adapter type.

Testing

• Migration logic verified
• Deployment currently blocked - needs immediate merge
