Subject: Add new sync (#1093)

* Add record migration

* Add database functions for inserting history

No real tests yet :( I would like to avoid running postgres lol

* Add index handler, use UUIDs not strings

* Fix a bunch of tests, remove Option<Uuid>

* Add tests, all passing

* Working upload sync

* Record downloading works

* Sync download works

* Don't waste requests

* Use a page size for uploads, make it variable later

* Aaaaaand they're encrypted now too

* Add cek

* Allow reading tail across hosts

* Revert "Allow reading tail across hosts"

Not like that

This reverts commit 7b0c72e7e050c358172f9b53cbd21b9e44cf4931.

* Handle multiple shards properly

* format

* Format and make clippy happy

* use some fancy types (#1098)

* use some fancy types

* fmt

* Goodbye horrible tuple

* Update atuin-server-postgres/migrations/20230623070418_records.sql
