.SYNOPSIS
    Create or update a Coolify SERVICE (Docker Compose multi-container stack)
    from a local project's compose file.

.DESCRIPTION
    Complements New-CoolifyApplication.ps1 (which only handles single-app
    Dockerfile builds via POST /applications/public). This script handles
    multi-container stacks via POST /services - the modern replacement for
    the deprecated POST /applications/dockercompose.

    Workflow:
      1. Resolve (or create) the target Coolify Project and Environment.
      2. Resolve the local server UUID.
      3. Read the docker-compose file from the project (default:
         docker-compose.coolify.yml). The compose must already satisfy the
         hard rules from docs/AGENTS-coolify-apps.md (no published 80/443,
         service-name DB host, healthchecks, named volumes, SERVICE_FQDN_*
         placeholders so Coolify can wire routes).
      4. POST /services with the raw compose + URL mappings (which service
         gets which FQDN).
      5. Push env vars from an optional .env file to the service.
      6. Trigger an initial deploy (unless -NoDeploy).

    Each mutating step asks for confirmation unless -Force is supplied.

.PARAMETER AppPath
    Local path of the project that contains the compose file. Required.

.PARAMETER AppName
    Service name in Coolify. Required. Becomes the resource name; Coolify
    auto-suffixes with a short UUID when it instantiates sub-services.

.PARAMETER ComposeFile
    Compose file name (relative to AppPath) or absolute path.
    Default: docker-compose.coolify.yml

.PARAMETER Fqdn
    Primary public URL, e.g. https://cotizador.urieljareth.org. The FQDN is
    mapped to the -PrimaryService in the compose via the `urls` payload.
    Required.

.PARAMETER PrimaryService
    The compose service name that should receive the -Fqdn. Default: 'web'.
    Set this to whatever your compose calls the main app service.

.PARAMETER ExtraUrls
    Optional hashtable mapping additional compose service names to FQDNs.
    Example: @{ api = 'https://cotizador-api.urieljareth.org' }
    Use when your compose exposes more than one public service.

.PARAMETER ProjectName
    Coolify project name. Created if missing. Default: 'default'.

.PARAMETER EnvironmentName
    Coolify environment name within the project. Default: 'production'.

.PARAMETER EnvFile
    Optional .env-formatted file. Each KEY=VALUE line is pushed to Coolify
    as a service-level env var. Lines starting with '#' are ignored.

.PARAMETER InstantDeploy
    Pass instant_deploy=true to the create call. Coolify starts the stack
    immediately after creation. Mutually exclusive with -NoDeploy.

.PARAMETER NoDeploy
    Do not trigger a deploy. Service is created with env vars but not started.
    Use this when you want to review in the UI before the first start.

.PARAMETER ServiceUuid
    Optional. If a service already exists in Coolify, pass its UUID to PATCH
    it (compose_raw, urls) in place instead of creating a new one.

.PARAMETER Force
    Skip per-step confirmation prompts.
