* Add support to set `created_at`
Discussed in
https://github.com/basecamp/fizzy/pull/1766#issuecomment-3637846074,
this allows users to import cards from another system with entries from
the past. For instance I'm importing all our Github issues (including
the closed onces) to Fizzy.
* Iron out published state tracking

Instead of writer pinning, we'll track the last transaction ID of each
write in the session. Then on each read we'll wait for the replica to
report that this transaction is available.
If it doesn't become available within a reasonable timeout, we'll
proceed anyway, and accept the possibility of a stale read.
The hope here is that most of the time, the replica is caught up in the
time between a write request and the following read request. If it's
not, we now have a little tolerance to wait for it, which hopefully
proves enough to stale reads are not encountered in normal use.
We also disable the writer affinity opt-out mechanism that we had
before, since we will no longer be using writer affinity at the load
balancer.
In order for model ordering to work as expected in tests, we need to
keep two properties:
- Fixtures are all created in the past
- Models sort in the order that they were created
This allows us to do things like this:
post cards_path, params: { ... }
created_card = Card.last
When using UUIDv7 PKs rather than sequential integers, we have to make
sure a couple of things happen in order for this still to be true:
- Fixtures should generate deterministic IDs that translate to UUIDs
that would have been created in the past (i.e. before today)
- Newly created objects must have enough precision in their timestamps
so that they sort in the order they were created, and their random
component doesn't come into play.
To solve this, we use the deterministic numeric ID as a number of
milliseconds after an early year. And we ensure that the new timestamps
we create have sub-millisecond precision.
These are mainly because the fixture's UUIDs are deterministic rather
than time-sortable, and more places where we need to correct the fixture
IDs as well.

This will prevent these from udpating live, but we will tackle that as part of live card
updates with page refreshes, which I will tackle soon.
Removes the creating status completely as well as the abandoned cards system. It will
always resume drafts if they exist, for a given collection and user.
