Semaphore v2.18 source (db/TemplateVault.go) shows FillTemplateVault
only loads the key when type==TemplateVaultPassword. With type left
as the default empty string, the vault key is stored but never
materialised at task-run time; ansible-playbook gets no password and
fails with 'Attempting to decrypt but no vault secrets found'.
Confirmed by patching live templates via PUT with type='password';
next task run succeeded.
