Updated the long descriptions and usage tips for the price trend change sensors in multiple languages (de, en, nb, nl, sv) to provide clearer guidance on detection mechanics and expected behavior during V-shaped price days.
Impact: Users will have a better understanding of how the sensors operate and can make more informed decisions regarding automation based on price trends.
Wrap most user-guide code examples in collapsible details sections to reduce visual noise while keeping Mermaid diagrams expanded.
Standardized summary labels across the user docs to a small set of readable patterns and removed technical or awkward wording from visible collapse titles.
Impact: User documentation is easier to scan, with long examples hidden by default and more consistent expand/collapse labels.
