Refactor IndexedDB document persistence to reuse data structures of desktop persistence (#4020) 

* Switch indexedDb document serialized struct from camelCase to snake_case

* Refactor and migrate old indexedDb format to the same shape as desktop persistence

* Avoid duplicate struct definitions in the desktop crate

* Refactor frontend message handling to consolidate auto-save document loading

* Code review

* Review
