fix: correct Statuses and Work Types sync to use picklist API

Problem:
- syncStatuses() and syncWorkTypes() were trying to query /Statuses/query
  and /WorkTypes/query endpoints which don't exist in Autotask API
- This caused 404 errors: 'File or directory not found'
- These are picklist values, not queryable entities

Solution:
- Changed syncStatuses() to use getPicklistValues('Tickets', 'status')
- Changed syncWorkTypes() to use getPicklistValues('TimeEntries', 'workType')
- Now follows same pattern as syncIssueTypes() and syncSubIssueTypes()
- Uses proper picklist API endpoint: /entity/entityInformation/fields

This fixes today's sync failures for statuses and work_types entities.
