HA expects \`name\` and \`unit_system\` as keys of the top-level
\`homeassistant:\` block, not as top-level integration names. Recent HA
versions tightened config validation, so this surfaced as
"Integration 'unit_system' not found" / "Integration 'name' not found"
warnings, blocking the automation reload that runs after saving an
automation in the UI.
Pre-existing bug, unrelated to OTBR — surfaced now because automation
edits trigger strict validation. Bonus: NixOS auto-populates
\`time_zone\` from the system locale once \`homeassistant\` is a real block.
