monograph: add sync support (#39)

* monograph: add sync support

* monograph: fix password field && improve syncing logic && fix delete endpoint

* sync: get rid of unnecessary .ToList & ToListAsync

* sync: AddIdsToAllDevices is no longer asynchronous

* monograph: simplify and fix several bugs

- we were sending the triggerSync event to all users instead of all devices
- asynchronous methods did not have the `Async` suffix
- we weren't properly replacing the deleted monograph

* monograph: fix minor issues
* fix publishing
* don't return deleted monograph in monographs/:id endpoint
* persist UserId when soft deleting monograph

* monograph: check soft delete status in several endpoints
