chore: initial baseline before refactoring

Initial snapshot of Home Assistant config (HAOS 2026.4.4)
prior to dashboard restructuring and helper YAML migration.

Pre-commit cleanup applied:
- Removed blueprints/switch_manager/ (9.4 MB stale, component already gone)
- Removed .storage/switch_manager
- Removed home-assistant.log.{1,old,fault}
- Removed zigbee2mqtt/configuration_backup_v{1..4}.yaml
- Removed zigbee2mqtt/database.db.tmp.2024-09-27 (1.5y old)
- Created empty themes/ to satisfy configuration.yaml include

.gitignore uses allowlist strategy for .storage/ to keep
all tokens, keys, and PINs out of version control.
