* 🎨🔥 do not store settings in config and make settings cache easier available
- remove remembering settings value in theme config
- if we need a cache value, we are asking the settings cache directly
- instead of settings.getSettingSync we use settings.cache.get
- added TODO:
- think about moving the settings cache out of api/settings
- we could create a folder named cache cache/settings
- this settings cache listens on model changes for settings
- decoupling
* 🔥 remove timezone from config
- no need to store in overrides config and in defaults settings
* 🎨 context object helper
- replace config.get('theme') by settings cache
* 🎨 replace config.get('theme') by settings.cache.get
* 🎨 adapt tests
* fixes from comments
closes#7688
- Use `/favicon.ico` and `/favicon.png` in blog app. Depending on type of storage (custom upload = local file storage), serves either from storage adapter with `read()` method or reads the bytes via `fs`.
- Redirects requests for `favicon.ico` to `favicon.png` if custom `png` icon is uploaded and vice versa.
- Redirect requests for `favicon.png` to `favicon.ico` if default icon is used (in `core/shared`).
- Changes the `{{asset}}` helper for favicon to not serve from theme assets anymore. It will either be served the custom blog-icon or the default one.
- The `{{@blog.icon}}` helper renders the url of the **uploaded** blog icon. It won't render the default icon.
