Idempotent provisioning, service soft-delete, Plans page redesign, doc updates

Part A: Fix duplicate Service creation on provisioning retry
- All 4 provisioning services use Service::firstOrCreate() keyed on
  subscription_id+service_type to prevent duplicates on queue retries
- HandleSubscriptionCreated sends notification before provisioning,
  no longer re-throws on failure
- RetryProvisioningCommand simplified to reuse existing Service records

Part B: Plans/Pricing page complete redesign
- Service type tabs (VPS, Dedicated, Web Hosting, MySQL)
- Billing cycle segmented toggle (monthly/quarterly/semi-annual/annual)
- Feature icons per service type, Popular/Best Value badges
- Stock indicators, effective monthly price calculations

Part C: Admin service soft-delete/archive
- Service model uses SoftDeletes trait
- Admin can archive and restore services
- Show archived toggle on services list
- Migration adds deleted_at column

Docs: Updated TASKS.md, CLAUDE.md, PROJECT_DEVELOPMENT.md, MEMORY.md
- Phase 3 marked complete, test counts updated (252 passing)
- SupportPal references replaced with standalone ticket system
- Frontend design skill background rule added
- Closed GitHub issues #3, #6, #7, #8, #9
