Pay Cat Connect Changelog

To support changes to the treatment of sleepovers in SCHADS, new fields have been added to the employee model:
- sleepoverSettings (optional object) with hasAgreedToWorkExtendedShifts (boolean) and grandfatheredShiftPenalties (boolean) properties.
- hasAgreedToWorkExtendedShifts indicates whether the employee has agreed to work extended shifts adjoining sleepovers, which affects overtime calculations under SCHADS.
- grandfatheredShiftPenalties if true, an employee will receive night shift penalty for all work attached to a sleepover (excluding where a higher penalty applies). If false, the sections before and after a sleepover are assessed individually.

GET /v1/business/{businessId}/list/tags now returns tag objects with name and award instead of plain tag-name strings.
GET /v1/business/{businessId}/employees now returns employees reshaped back into the front-facing CostingEmployee contract instead of the previous minimal summary payload.

Employee validation now accepts classificationOverride together with schadsSector, and employment agreement lookup continues to prefer the explicit classification override when both are present.
Employee email and business contactEmail inputs are now trimmed before validation/persistence to allow for accidental leading/trailing whitespace without causing validation failures.

Added POST /v1/business/{businessId}/awards/update to submit KeyPay award update jobs on non-live businesses using a user-supplied awardName, including specific handling for KeyPay award-update throttling so requests return a clear retryable error when KeyPay responds with 400 and "A maximum of 2 running award installations is allowed" (work in progress while broader award-update flows are being implemented).

Business API responses now include keypayBusinessId and crmName.
Updated the static pay category label definitions used for costing explanation labels.
