- `customThemeSettings` feature is GA so any conditionals can be cleaned up
- removed conditional loading of custom theme settings and associated API routes
- removed event trigger for reloading custom theme settings when the feature flag is toggled
- removed flag from labs GA list
- throughout the theme activation flow there are several missing awaits and necessary async keywords
- we should be waiting on these processes, not letting them complete indeterministically

Custom theme settings sync and cache population had been left to complete in the background as it wasn't essential for it to be complete for the front-end to start. However that was causing problems for the API where theme activation and custom theme settings list requests happen very close together, with the latter often not containing the theme settings data when it is expected to.
- changed `activationBridge.*` methods to `async` so they can `await` the completion of custom theme settings sync before activating a theme

Ghost allows different themes to have the same `name` value in `package.json` but gives them a custom name based on the zip file used to upload it. The custom theme settings service however was always using the package.json name meaning that when syncing a theme with a duplicate name it was overwriting the settings for all other themes.
- bumped `@tryghost/custom-theme-settings-service` which changes the `.activateTheme()` signature to accept a theme name as the first argument
- updated our calls to `.activateTheme()` to pass Ghost's known theme name as the first argument so we're always syncing with the correct `theme` field value in the `custom_theme_settings` table

- bumped `@tryghost/custom-theme-settings-service` so it throws a more appropriate `ValidationError` when setting keys don't exist or a select value is not known
- changed the custom theme settings service to have a `.init()` method which creates an instance of the service under `.api` so that we're able to create the instance at a particular point in the boot process when we know the models have been initialised
- there were problems in tests because the service was being initialised through the require chain before models were initialised through the boot process
- fixed incorrect `camelCase` of resource name in API responses

- added `@tryghost/custom-theme-settings-service` as a dependency
- `core/server/services/custom-theme-settings` creates an instance of the new service passing in the model used for storing the setting keys/values and a cache instance
- requiring `core/shared/services/custom-theme-settings-cache` creates a cache instance, it has no dependencies so can be required anywhere and the first require will initialize the shared instance
- updated the theme activation bridge to trigger the theme settings service to sync the newly activated theme settings and populate the cache
- updated theme validation to pass `labs` through as an option so that we get custom theme settings back as part of the checked theme as that's what is passed to the custom theme settings service
- This is a slightly weird thing, but the intention is to highlight that there are 3 different code paths that can activate a theme
- Ideally we want to unify all the codepaths more, but for now this at least helps us see what is happening where
