The context passed to the database layer will auto-close when the HTTP
client disconnects. This will cancel any running query, which is the
expected behaviour. Now this no longer results in an error being logged
in the database layer. Instead, a message is logged at debug level.
The API layer is also adjusted to silence logging of `context.Canceled`
for certain operations, most notably getting all jobs and getting all
tasks of a job. These calls occur when the webapp reconnects after a
restart of the Manager. That may trigger a refresh of the page, which
immediately aborts any pending API calls. This is normal and should not
cause errors to be logged.
Change the package base name of the Go code, from
`git.blender.org/flamenco` to `projects.blender.org/studio/flamenco`.
The old location, `git.blender.org`, has no longer been use since the
[migration to Gitea][1]. The new package names now reflect the actual
location where Flamenco is hosted.

Add a timeout when fetching a job from the persistence layers.
It's my intention to add more timeouts, so this also introduces some code
to make it easier to test that a context has a deadline set.
Deduplicate API implementation code to fetch a job from the persistence
service.
Almost no functional changes. Checking that the requested job UUID is
actually a valid UUID is now consistently done on all fetches. This is
not a functional change in normal Flamenco operations, where only valid
UUIDs are used anyway.
Add a small wrapper around github.com/google/uuid. That way it's clearer
which functionality is used by Flamenco, doesn't link most of the code to
any specific UUID library, and allows a bit of customisation.
The only customisation now is that Flamenco is a bit stricter in the
formats it accepts; only the `xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx` is
accepted. This makes things a little bit stricter, with the advantage
that we don't need to do any normalisation of received UUID strings.
Add `fetchJobTasks` operation to the Jobs API. This returns a summary of
each of the job's tasks, suitable for display in a task list view.
The actually used fields may need tweaking once we actually have a task
list view, but at least the functionality is there.
