72ab319d37 fix(db-*): ensure consistent sorting even when sorting on non-unique fields or no sort parameters at all (#12447)
The databases do not keep track of document order internally so when
sorting by non-unique fields such as shared `order` number values, the
returned order will be random and not consistent.

While this issue is far more noticeable on mongo it could also occur in
postgres on certain environments.

This combined with pagination can lead to the perception of duplicated
or inconsistent data.

This PR adds a second sort parameter to queries so that we always have a
fallback, `-createdAt` will be used by default or `id` if timestamps are
disabled.

e90ff72b37 fix: reordering draft documents causes data loss (#12109)
Re-ordering documents with drafts uses `payload.update()` with `select:
{ id: true }` and that causes draft versions of those docs to be updated
without any data. I've removed the `select` optimization to prevent data
loss.

Fixes #12097

d963e6a54c feat: orderable collections (#11452)
Closes https://github.com/payloadcms/payload/discussions/1413

### What?

Introduces a new `orderable` boolean property on collections that allows
dragging and dropping rows to reorder them:

### Why?

[One of the most requested
features](https://github.com/payloadcms/payload/discussions/1413).
Additionally, poorly implemented it can be very costly in terms of
performance.

This can be especially useful for implementing custom views like kanban.

### How?

We are using fractional indexing. In its simplest form, it consists of
calculating the order of an item to be inserted as the average of its
two adjacent elements.
There is [a famous article by David
Greenspan](https://observablehq.com/@dgreensp/implementing-fractional-indexing)
that solves the problem of running out of keys after several partitions.
We are using his algorithm, implemented [in this
library](https://github.com/rocicorp/fractional-indexing).

This means that if you insert, delete or move documents in the
collection, you do not have to modify the order of the rest of the
documents, making the operation more performant.
