PPR UI - Unable to Complete CL Registration - Life

From OPs ticket https://sbc-registries.atlassian.net/browse/ITOPS-190495
User walking through the steps indicates a commercial lien for a motor vehicle (crane not listed) for a 1 year period. after all fields are completed - user received an error of registration length. Going back to the registration length - tried 2 years, then review and confirmed - error still appears.

Update from OPs ticket, the user was entering "1 year" instead of 1 for the life. Update UI validation?
- [ ] Restrict registration field length to numbers

UI review and confirm validation error, unable to enter life.
