docs(audits): update scores after Swagger and accessibility improvements

- Calendar: 92 → 94 (documentation 95→98, frontend 88→90, ux 85→88)
- Contacts: 93 → 94 (documentation 88→92, frontend 88→90, ux 82→85)
- Todo: 93 → 94 (documentation 90→95, frontend 85→88, ux 82→85)
All three now have: Swagger API docs, skip-to-content, ARIA navigation labels
