Employees and admins can pick, drop, swap, and manage coverage through
GET/POST/DELETE /api/shifts. Roster PUT accepts optional email for portal
identity. Slack slash commands and App Home admin modals stay in place.

* fix(cutover): write Slack secrets into empty Terraform shells
DescribeSecret succeeds on HCP-created shells with no version, so skip-if-exists left roster and Slack tokens unset.
* feat(infra): migrate afterhours to HCP Terraform (PLAT-74)
Replace the mgmt SAM stack with a prod-only HCP workspace, in-repo hcptf IAM, stub Lambdas, and zip CD on push to main.
* fix(cutover): retry DDB unprocessed items and skip past at() holidays
Unprocessed BatchWriteItem rows and leftover past at() schedules would drop roster data or abort holiday recreation during prod cutover.
