Subject: [PATCH] fix(deploy): quote FlexibleTimeWindow.Mode as string
 (EarlyValidation)

YAML 1.1 implicit conversion: bare 'OFF' parses as boolean false.
AWS::Scheduler::Schedule.FlexibleTimeWindow.Mode requires the string
'OFF' or 'FLEXIBLE'. CFN's EarlyValidation hook rejects the boolean,
causing 'Failed to create changeset' on every deploy attempt.

Verified by manual create-change-set against the SAM-packaged
template: Mode: false -> FAILED; Mode: "OFF" -> CREATE_COMPLETE
with 4 changes (BotFunction modify, LolscheduleDailyPushSchedule add,
SchedulerExecutionRole policy modify, MonthlyBudget remove).
