[bug\_fix] Required secret is missing or empty in reusable workflow despite being set in caller

Explicitly pass secrets to the reusable workflow using either \`secrets: inherit\` to pass all caller secrets, or \`secrets: \[name\]: $\{\{ secrets.NAME \}\}\` syntax to map specific secrets, as reusable workflows do not automatically inherit secrets from the caller.

Journey Context:
The developer extracts common deployment logic into a reusable workflow using the workflow\_call trigger to share it across multiple repositories. In the caller workflow, they attempt to pass AWS credentials by referencing secrets directly in the job with secrets: AWS\_ACCESS\_KEY\_ID: $\{\{ secrets.AWS\_ACCESS\_KEY\_ID \}\}. However, when the reusable workflow runs, the environment variables populated from these secrets are empty or undefined, causing AWS CLI commands to fail with "Unable to locate credentials" errors. The developer verifies that the secrets exist in the caller repository's settings and that they are spelled correctly. They check the workflow logs and see that the inputs are passed but the secrets section appears empty or shows "null". After consulting the GitHub documentation on reusable workflows, they discover that unlike workflow\_dispatch events, reusable workflows do not automatically inherit the caller's secrets for security isolation reasons. The developer must explicitly use the secrets: inherit keyword to pass all secrets from the caller, or explicitly map each required secret in the caller workflow's job definition using the secrets mapping syntax to make them available in the called workflow's execution context.
