fix: add missing data column to user_profiles migration

[lane711]

Summary

• The user edit page (/admin/users/:id/edit) crashes with a 500 error because the user_profiles table is missing the data column
• PR feat: add configurable user profile fields plugin #747 added code querying SELECT ... data FROM user_profiles but placed the migration file in the wrong directory (src/db/migrations/ instead of migrations/), so it was never bundled or executed
• Adds the missing column via both the CREATE TABLE (fresh installs) and a new ALTER TABLE migration (existing databases)

Changes

File	Description
packages/core/migrations/032_user_profiles.sql	Add data TEXT DEFAULT '{}' to CREATE TABLE
packages/core/migrations/035_user_profiles_data_column.sql	New ALTER TABLE migration for existing DBs
packages/core/src/db/migrations-bundle.ts	Regenerated to include migration 035
my-sonicjs-app/migrations/018_user_profiles.sql	Add data column for app-level consistency
packages/core/src/db/migrations/0011_user_profiles_data.sql	Removed (was in wrong directory)

Root Cause

PR #747 (configurable user profile fields plugin) introduced a migration file 0011_user_profiles_data.sql in packages/core/src/db/migrations/. However, the migration generator script (scripts/generate-migrations.ts) reads from packages/core/migrations/. The migration was never bundled, so the data column was never created, causing the user edit page to crash when it queries that column.

Testing

• TypeScript compilation passes (tsc --noEmit)
• Migrations bundle regenerated successfully with 34 migrations
• Migration runner already handles duplicate column errors gracefully
• E2E tests (CI)

Checklist

• Code follows project conventions
• No new TypeScript errors introduced
• Existing e2e test 38-user-profile-edit.spec.ts covers this page
