bef65aa8a2 Fixed email count check in email-analytics service
no issue

- raw knex `.count()` does not return a straight number, we need to handle an array of rowDataPacket objects

a84ec49854 Added no-emails guard check when fetching latest email events
no issue

- replicates the same guard used in `fetchLatest()` to prevent contacting Mailgun when there are no emails in the database

7bbf644d0d Added email analytics service ()
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
