Release 1.4.5 🌞

Removes the charge hold-off where the direction is fixed, adds 600 W fuse groups, and corrects the SoC limit state labels.

🩹 Fixes

No charge hold-off in manual and store_solar by @serahug in #1665 (fixes #1664): switching from smart to manual with a negative manual power left the battery idle for about 60 s before it started charging. The hold-off now only applies to the smart modes, where the direction can flip on its own.
SoC limit state labels by @Golden007-prog in #1738 (fixes #1677): value 1 is full and 2 is limiting at the minimum SoC; English, German and Polish had them the other way round. French gets the sensor name and state labels.

600 W fuse groups by @kes1 in #1739 (fixes #1493): group600_1200 and group600_2400 for setups limited to 600 W feed-in, such as plug-in systems in Switzerland. Existing fuse group selections are kept.
paho-mqtt requirement relaxed to >=2.1.0 by @surfer1264 in #1683

Tests migrated to pytest-homeassistant by @balloobbot in #1750: the Core-maintained test harness replaces pytest-homeassistant-custom-component.
