Refactors VM Schedule to make it more generic & add option to schedule min & max for autoscaling groups

[vishesh92]

Description

This PR refactors the VM schedule to make it more generic and allow creation of scheduled actions based on cron format for other resources with minimal changes. Apart from the existing schedules for VM, this PR adds support for scheduling min & max members of a autoscaling group.

Pull request overview

This PR generalizes the existing VM scheduling feature into a resource-agnostic “Resource Schedule” system (API, persistence, workers, and UI), while keeping legacy VM schedule APIs as deprecated wrappers.

Changes:

• Introduces generic create/list/update/deleteResourceSchedule APIs with a worker-based execution model (BaseScheduleWorker + VMScheduleWorker).
• Migrates DB schema from vm_schedule / vm_scheduled_job to resource_schedule / resource_scheduled_job and adds resource_schedule_details.
• Updates the UI and integration/unit tests to use the new resource schedule APIs (with legacy VM schedule APIs mapped to the new backend).

• apiParams is populated only from createResourceSchedule. If a role can list schedules but cannot create them, $getApiParams('createResourceSchedule') returns {}, and the template’s apiParams.<param>.description accesses will throw even though the “Add” button is disabled. Consider populating apiParams from whichever schedule API is available (e.g. create/update) and/or guarding template access with optional chaining / defaults so the tab can render read-only.
  ui/src/views/compute/ResourceSchedules.vue:375
• The watcher on resource is deep: true, so any reactive change inside the resource object (e.g. VM state updates) will re-trigger fetchSchedules() and can cause unnecessary API traffic. Watching only resource.id (or using a shallow watch) should be sufficient and avoids repeated list calls.
