Fix: Preserve template vaults when updating templates without vault field

[Copilot]

Updating a template via PUT /api/project/{project_id}/templates/{template_id} without including the vaults field in the request body deletes all existing vaults.

Changes

• db/sql/template.go, db/bolt/template.go: Only call UpdateTemplateVaults when template.Vaults != nil
  • nil (field omitted) → preserve existing vaults
  • [] (empty array) → clear all vaults
  • [...] (populated array) → update vaults

// Before
func (d *SqlDb) UpdateTemplate(template db.Template) error {
    // ... update template fields ...
    err = d.UpdateTemplateVaults(template.ProjectID, template.ID, template.Vaults)
    return err
}

// After
func (d *SqlDb) UpdateTemplate(template db.Template) error {
    // ... update template fields ...
    if template.Vaults != nil {
        err = d.UpdateTemplateVaults(template.ProjectID, template.ID, template.Vaults)
    }
    return err
}

• db/bolt/template_vault_test.go: Add tests covering nil, empty array, and explicit update scenarios

<issue_title>Problem: Unable to Update an Ansible Project Template when there are existing Vaults</issue_title>
<issue_description>### Issue

When trying to Update an existing Ansible Project Template:

HTTP PUT http://{{host}}:{{port}}/api/project//templates//

{
   ....
    "vaults": [
        {
            "name": "TEST",
            "type": "password",
            "vault_key_id": 7
        }
    ]
}

If the template already has a vault with the same template_id, vault_key_id, name which are basically the unique constraint in the table project__template_vault

400 Bad Request http error is generated.
