feat: manual link customer to e-conomic (v1.3.58)

- Added POST /api/v1/customers/{id}/link-economic endpoint
- Allows manually setting economic_customer_number for customers without CVR
- Useful for vTiger customers that can't auto-match via CVR or name
- Updates last_synced_at timestamp when linking
