Override the parallel diff lines property with new data

See merge request gitlab-org/gitlab!40131

Doing it this way allows us to:
1. Allow all existing code to work without changing a lot
2. Migrate all the code away from this property
once this feature has been fully rolled out

Update factory doc with common change information

The files_count cache column was created with the assumption that the
number of files never changes throughout the life of a diff. However,
we have discovered the DeleteDiffFilesWorker, which removes them (and
sets the state of the diff to :without_files) in some limited cases.

This MR updates the cache columns (both commits_count and files_count)
so they will be re-recorded on every update. Since updates are rare,
the additional cost of this should be very low.

Improve error message for job configs that fail to match an entry

This is behind the async_pages_move_project_rename feature flag. When
it's enabled and a project is renamed, we do not move the Pages
directory in Puma - instead, we schedule a Sidekiq job to perform the
move.

We already weren't checking the return value of
`Gitlab::PagesTransfer#rename_project`, so this shouldn't introduce any
failure cases that weren't there already.

Fix: already initialized constant warnings for HTTPError

Closes #239380

Currently Vault Secrets are using partially hardcoded configuration
for the authentication method. While the Vault server URL and the
role name for JWT authentication method can be configured with the
variables, the authentication method path is hardoced to `jwt`.
This may limit the usability of our solution.

This change makes this value configurable with the `VAULT_AUTH_PATH`
variable (similar to how `VAULT_SERVER_URL` and `VAULT_AUTH_ROLE`
are being used already) and ensures that in case when the variable
is not defined by the user, it will fall-back to the `jwt` value
that we have hardcoded now.

Use active user count instead of historical max

Closes #224681

See merge request gitlab-org/gitlab!37916

"User count threshold" banner should use
active user count instead of historical max
to reflect the current state.

The worker specs should just test the worker's behaviour, which is
calling the service. The service specs should test the operations on
disk.

When we rename a project, we call Gitlab::PagesTransfer to move any
pages directory on disk. This makes it convenient to use that class
through Sidekiq instead, so that Puma no longer needs access to Pages
NFS mounts.
