home-assistant: fix initial config - remove !include directives

The !include directives for automations/scripts/scenes reference files
that don't exist on fresh install, causing HA to enter recovery mode
which ignores trusted_proxies. Simplified to minimal config with just
default_config and http block - HA adds the rest during onboarding.
