0.1.1

Added

• Added a new architecture proposal documenting a dedicated service-account and
  privilege-hardening plan for BMGateway, including the current permission
  inventory, sudo scope, systemd hardening opportunities, and phased
  implementation guidance.
• Added a backlog proposition that references the service-account and
  privilege-hardening proposal so the investigation can be reused when the work
  is scheduled.
• Added editable gateway settings for MQTT broker and Home Assistant topic
  parameters, and updated the default MQTT username placeholder from
  homeassistant to mqtt-user.
• Documented Home Assistant auto-discovery in user-facing English, including
  the required MQTT broker path and a clearer explanation of
  Home Assistant MQTT discovery.
• Split editable settings into separate Gateway, MQTT, and Home Assistant
  sections and added inline help text for MQTT, Home Assistant, web, gateway,
  and Bluetooth options.
• Documented MQTT authentication behavior, retained discovery/state defaults,
  and why the Home Assistant discovery prefix defaults to homeassistant.
• Added a visible MQTT broker connection status row to the settings page.
• Added a Settings action to republish Home Assistant MQTT discovery and current
  device state to the configured broker on demand.
• Compacted the recent raw readings table on history pages with shorter column
  labels, smaller table text, non-wrapping cells, and a bounded scroll area.
• Made device IDs editable from the device edit form with validation, including
  stored-history ID collision checks and history-table renaming when an ID
  changes.
• Validated editable device IDs so MQTT topic paths stay limited to letters,
  numbers, underscores, and hyphens.
• Updated device ID renames to also normalize stored raw/archive metadata such
  as the device name, type, and MAC address so charts do not split old and new
  labels after a rename.
• Filtered the settings storage summary to configured devices so removed test
  devices no longer appear in the normal settings view.
