fix: Resolve GraphQL DateTime and JSON serialization errors

Fixed two critical GraphQL schema issues preventing dashboard data loading: **Backend Changes:** - Changed child.birthDate from DATE to TIMESTAMP type in entity and database - Updated TypeORM entity (child.entity.ts:23) - Migrated database column: ALTER TABLE children ALTER COLUMN birth_date TYPE TIMESTAMP - Added JSON scalar support for activity metadata field - Installed graphql-type-json package - Created JSONScalar (src/graphql/scalars/json.scalar.ts) - Updated Activity.metadata from String to GraphQLJSON type - Auto-generated schema.gql with JSON scalar definition **Frontend Changes:** - Fixed Apollo Client token storage key mismatch - Changed from 'access_token' to 'accessToken' to match tokenStorage utility - Enhanced dashboard logging for debugging GraphQL queries **Database Migration:** - Converted children.birth_date: DATE → TIMESTAMP - Preserves existing data (2023-06-01 → 2023-06-01 00:00:00) Resolves errors: - "Expected DateTime.serialize() to return non-nullable value, returned: null" - "String cannot represent value: { ... }" for activity metadata 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
