Don't block on import lock to queue async assay import

[labkey-jeckels]

Rationale

Users are seeing an indefinite progress bar when attempting to queue an asynchronous assay import when another asynchronous background is already running. That import is taking a while because it's running an expensive transform script.

Changes

• Don't acquire the import lock to queue the asynchronous import, since we aren't actually going to be doing the import

Tasks

• Claude Code Review
• Manual Testing @labkey-tchad
  • Create an assay design and set it to import in the background
  • Make the import slow - could use an expensive transform script, or add a Thread.sleep() or single-thread breakpoint in DefaultArrayRunCreator inside the section with the protocol import lock:

    platform/api/src/org/labkey/api/assay/DefaultAssayRunCreator.java

    Line 322 in 790e616

    if (transaction.getAuditId() == null)

  • Do some assay imports, submitting before the previous one(s) have finished running as a pipeline job
  • Make sure the progress bar dialog clears immediately instead of waiting for the current job to finish
• Test Automation - N/A
