ci: use ubuntu-slim for lightweight workflows (deepmodeling#5742)

## Summary
- switch lightweight label, mirror, TODO, and pass aggregation jobs to
ubuntu-slim
- switch the Python test duration aggregation job to ubuntu-slim
- keep build and test execution jobs on their existing runners

## Validation
- python YAML parse for all workflow files
- git diff --check
- ruff check .

Note: ruff format --check . still reports pre-existing formatting in
dpa_adapt/cli.py, which is unrelated to this workflow-only change.

## Summary by CodeRabbit

* **Chores**
* Updated several GitHub Actions jobs to run on a slimmer Ubuntu runner.
* Applied this environment change across build, test, packaging,
labeling, mirroring, and maintenance workflows.
  * No workflow steps, dependencies, or job logic were changed.
