Persistent HVAC and SMART Aicro support

[1.1.2] – 2026-04-07

Added

• Persistent HVAC mode support, the ability to toggle Smart Schedule for heating/cooling (this will trigger an API call). (#43)
• Full Smart AC Control support.
• New /zones/{id}/set parameter heating_mode (0 = off, 1 = HEAT, 2 = COOL).
• Ability to switch an entire zone on or off with a single API call via /zones/set/ (as either an overlay or a persistent change).
• Automatic database history purge via CLI and manual purge via API (/purgehistory/now/).
• This changelog. (#44)

Changed

• Improved synchronization logic between HomeKit state and cloud‑derived zone data (HomeKit device types now take precedence and names are stored correctly).
• heating_enabled=true now restores the last known active heating or cooling mode.
• Updated documentation to reflect persistent HVAC behavior and Smart AC Control support.
• Updated index.html to support Smart AC Control (COOL modes/colors) and persistent Smart Schedule switching.
• Updated unit tests to cover new and modified features.

Fixed

• Corrected case‑sensitivity issues in UUID comparisons.
• Home Assistant add‑on now only moves the database when the public database does not already exist.
• Removed large top‑page spacing in index.html.
