Always use local time for job compiler timestamp variable

The 'Simple Blender Render' job compiler script uses a `{timestamp}`
variable to determine the render output path. This variable is now set
to the local time, rather than UTC.

This fixes #104219: Unit tests are timezone-dependent

The solution uses Go `time.Local` timezone to satisfy unit tests
assertions using a Mock clock. The timezone of the local workstation
running the tests.

 - The webapp automatically reloads after a disconnect, when it reconnects to Flamenco Manager and sees the Manager version changed [#104235](https://projects.blender.org/studio/flamenco/pulls/104235).
 - Show the configured Flamenco Manager name in the webapp's browser window title.
 - Workers can be marked as 'restartable' by using the `-restart-exit-code N` commandline option. More info in the [Worker Actions documentation](https://flamenco.blender.org/usage/worker-actions/).
+- The `{timestamp}` placeholder in the render output path is now replaced with a local timestamp (rather than UTC).
