Steps to reproduce:

1. Run composer server shell
2. Inside the container, run wp
3. Observe Error: Site 'your-project.altis.dev.' not found. Define DOMAIN_CURRENT_SITE in 'wp-config.php' or use --url= to override.

This occurs because we set the host name using COMPOSE_PROJECT_NAME and COMPOSE_PROJECT_TLD:

However, the latter is not defined, so we get a trailing .

Worse, COMPOSE_PROJECT_NAME is inconsistent; usually, it refers only to the subdomain:

However, the docker-compose configuration instead sets this to the full domain:

These need to be made consistent; this probably should have been done in #341 and #465, but we missed it. (You can verify this by running env inside composer server shell)

We also need to fix the HTTP_HOST override, as if we're in Codespaces, the TLD is not set at all. COMPOSE_PROJECT_NAME seems to only be used in this code, so it should be fine to update this.

I would suggest we introduce a new environment variable instead of reusing this, since COMPOSE_PROJECT_NAME has an existing specific purpose.

Acceptance criteria:

• COMPOSE_PROJECT_NAME contains only the docker-compose project name
• COMPOSE_PROJECT_TLD contains the TLD inside the shell
• ALTIS_DEFAULT_HOST contains the default HTTP_HOST
• Running wp with no --url parameter inside the shell uses ALTIS_DEFAULT_HOST correctly
