feat: rework compose config to be more modular

[jippi]

Context

• compose.default.yaml is what the end-user would see by default
• compose.yaml is now untracked by git (so owned by the server owner)
• Folks using Portainer etc. can use docker compose config to get the generated configuration from the includes and paste it into their Portainer UI

Changes

• Ship a compose.default.yaml containing the default file folks will copy during setup
• Use granular include to tweak the configuration, including
  • Adding/removing each individual service
    • Proxy / Proxy ACME
    • Web
    • Cron
    • Worker
    • DB
    • Redis
  • Wether each service should expose its ports to the host
  • Wether each service should have a static container name
  • Wether each service should have docker compose build configuration
  • Wether each service should have dependency on other containers health
• Remove _PROFILE env keys to disable services, since you can just NOT include them now
• Easy off-ramp/customization since end-user own the compose.yaml file
  • Adding new services
  • Implement their own service configuration if the include versions do not match their preferences
