fix: surface a00.un API errors + document dueDate-clearing limitation (v0.4.15)

- fw_client: detect nested a00.un errors (previously silent-failed as success)
- update_task: add clear_due_date=True parameter that returns a clear error
  explaining the Family Wall API cannot clear dueDate once set
- SPEC.md: document all tested clearing candidates and their API responses,
  add Fehlerstruktur-Varianten section
- Verified: dueDate cannot be removed via any form-encoded value; all invalid
  date strings are rejected via a00.un.un (silently swallowed before this fix)
