Silence retryable SQLite lock errors from docket.worker logger

[devin-ai-integration]

closes #19771

PR #18957 added a log filter to suppress noisy SQLite "database is locked" errors from the uvicorn.error logger. However, when using flow.serve() with SQLite, background tasks like mark_deployments_ready run through docket and log errors through the docket.worker logger, which was not covered by the original fix.

This PR extends the existing SQLite lock log filter to also filter the docket.worker logger, silencing the harmless but alarming error messages that users see during onboarding.

Changes

• Add docket.worker logger to the SQLite lock log filter installation
• Add test coverage for the docket.worker logger case
