refactor: remove dead code — orphaned files, unused types and functions

Delete 3 orphaned files (SubNav, TopBar, problems.ts), remove 4 unused
type definitions from pmr.ts (ViewId, NavItem, ReferralFormData, Problem),
trim types/index.ts to only Phase, and remove unused utility functions
(calculateSkillOffset, formatBootLine, getProfileContent, DotColorName).
