[bug\_fix] Input required and not supplied: token or secret appears empty/undefined when calling a reusable workflow from a caller workflow

In the caller workflow, explicitly pass secrets using \`secrets: inherit\` to pass all secrets, or \`secrets: MY\_SECRET: $\{\{ secrets.MY\_SECRET \}\}\` to pass specific ones. In the called \(reusable\) workflow, define the secret in the \`on.workflow\_call.secrets\` mapping. The root cause is that secrets are not automatically inherited by reusable workflows for security isolation; they must be explicitly wired through the interface contract.

Journey Context:
You refactor a deployment workflow into a reusable workflow in \`.github/workflows/deploy-reusable.yml\`. The caller workflow passes \`environment: production\`. The reusable workflow tries to use \`secrets.AWS\_ACCESS\_KEY\_ID\` but it's empty. You add debug steps and see the secret context exists but is blank. You search 'reusable workflow secrets empty' and find discussions about inheritance. You try adding \`secrets: inherit\` to the caller's \`uses\` step, but get a workflow validation error because the called workflow doesn't declare the secret inputs. You then add \`secrets: AWS\_ACCESS\_KEY\_ID: description: 'AWS Key' required: true\` under \`on.workflow\_call\` in the reusable workflow, and pass it explicitly from the caller. It works because the secret is now explicitly mapped through the workflow interface.
