- added `bread` util that acts as a wrapper for the provided model, if we have any business functionality needed when settings are added/removed then it will go here
- added primary "server" service that handles syncing of custom theme data extracted from a theme with the settings that are in the database and exported as "Service". Syncing rules on theme activation:
- if a new setting is seen, create it with the default value
- if a setting has it's type changed, remove it and create a new setting with the default value
- if a select setting's value is not a valid option, reset it to the default value
- added shared "frontend/server" service that exposes an in-memory cache of key/value pairs for the currently active theme
no issue
- fixed destructuring error when creating instances of `EmailAnalyticsService` or `EventProcessor` with no options object
- fixed unprocessable complained event incrementing complained count rather than unprocessable count
- fixed `fetchAll()` and `fetchLatest()` returning `undefined` instead of a blank EventProcessingResult
refs https://github.com/TryGhost/Ghost/pull/12541
- make `EventProcessor` a super-class designed to be inherited from in consumer applications for application-level implementation
- helps to keep application-level concerns for event handling (eg, what to do with spam complaints) and things like application database knowledge in the consumer
- removed all database knowledge from `EmailAnalyticsService`
- requires a `queries` option to be passed in that lets the consuming application provide knowledge and define how fetched stats should be aggregated

requires https://github.com/TryGhost/Ghost/pull/12457
- updates stats aggregator to calculate and store an open rate for each member
- uses two queries because I couldn't find a reasonable approach to perform the update in a single query as per the email aggregation
- benchmarked locally at <1sec/1000members
- will not store an open rate unless the number of tracked emails sent to a member is above a certain threshold (defaults to 5) to avoid new members being heavily weighted
- fixes typo in EmailAnalytics that was stopping member stats from being aggregated
no issue
- added `EmailAnalyticsService`
- `.fetchAll()` grabs and processes all available events
- `.fetchLatest()` grabs and processes all events since the last seen event timestamp
- `EventProcessor` passed event objects and updates `email_recipients` or `members` records depending on the event being analytics or list hygiene
- always returns a `EventProcessingResult` instance so that progress can be tracked and merged across individual events, batches (pages of events), and total runs
- adds email_id and member_id to the returned result where appropriate so that the stats aggregator can limit processing to data that has changed
- sets `email_recipients.{delivered_at, opened_at, failed_at}` for analytics events
- sets `members.subscribed = false` for permanent failure/unsubscribed/complained list hygiene events
- `StatsAggregator` takes an `EventProcessingResult`-like object containing arrays of email ids and member ids on which to aggregate statistics.
- jobs for `fetch-latest` and `fetch-all` ready for use with the JobsService
- added `initialiseRecurringJobs()` function to Ghost bootup procedure that schedules the email analytics "fetch latest" job to run every minute
