Changes

CLI Feature Expansion: Billing, DNS, Docker, and VM Operations

Layer / File(s)	Summary
Billing command hierarchy cmd/billing/billing.go, cmd/billing/catalog/..., cmd/billing/payment_methods/..., cmd/billing/subscriptions/...	Introduces billing command group with catalog list (item filtering by category/name), payment-methods list/delete/set-default, and subscriptions list/enable-disable auto-renewal subcommands, each with API integration and optional flag handling.
DNS command hierarchy cmd/dns/dns.go, cmd/dns/records/..., cmd/dns/snapshots/...	Introduces dns command group with records subcommands (list/delete with filters/update/validate/reset) and snapshots subcommands (list/get/restore), including zone operation request builders.
Root command registration cmd/root.go	Imports and registers billing and dns command groups alongside existing vps and version commands.
VPS Docker project management cmd/vps/docker/..., cmd/vps/vps.go	New docker subcommand group with full CRUD: list/get/create/update/delete projects, containers/logs inspection, start/stop/restart lifecycle controls; includes project creation request builders with environment variable support.
VPS virtual machine operations cmd/vps/virtual_machines/purchase.go, cmd/vps/virtual_machines/setup.go, cmd/vps/virtual_machines/restart.go, cmd/vps/virtual_machines/virtual_machines.go	New purchase, setup, and restart subcommands for VMs, with complex request builders assembling flags for data center selection, OS template, networking, authentication, backups, and post-install scripts; updates group description.
PTR record enhancements cmd/vps/ptr/create.go, cmd/vps/ptr/delete.go, cmd/vps/ptr_create.md, cmd/vps/ptr_delete.md	Updates create and delete to accept IP address ID as second argument; adds --domain flag to create command for specifying PTR record domain.
API endpoint version migrations cmd/vps/actions/, cmd/vps/backups/, cmd/vps/data_centers/, cmd/vps/firewall/, cmd/vps/post_install_scripts/, cmd/vps/public_keys/, cmd/vps/templates/, cmd/vps/virtual_machines/	Updates 25 existing command endpoints: actions (get/list), backups list, data centers list, firewall get, post-install scripts (list/delete), public keys (create/delete/list), templates (get/list), and virtual machines (get/list) now target newer API method versions with matching parameter type updates.
Command documentation docs/hapi*.md, docs/hapi_billing*.md, docs/hapi_dns*.md, docs/hapi_vps_docker*.md, docs/hapi_vps_vm_*.md	Adds 76+ markdown pages documenting the new billing, DNS, Docker, and VM purchase/setup commands; updates existing index and SEE ALSO sections; standardizes help descriptions across the hierarchy.
