Develop a dedicated library for unit formatting (e.g., '30 °C' from 'value = 30', 'unit = c') to ease integration for other apps and improve modularity. This requires significant refactoring and moving translations out of the app module.
Would ease integration by other apps, so they can correctly format something like `value = 30`, and `unit = c` to `30 °C`. High effort, as it requires a lot of refactoring to make this modularized. We also need to move translations out of the app module, and Weblate translations are a mess (they don't respect the order of the English file) Remaining work: - [x] Percent “unit” - Translations for: - [x] Temperature - [x] Distance - [x] Speed - [x] Precipitation - [x] Pressure - [x] Air pollutant concentration - [x] Pollen concentration - [x] Duration
