fix: streamline cleanup and port workflows

[weidonglang]

Summary

• split Cleanup into Quick cleanup, Move and recover space, and Advanced tools task views
• add guided cleanup and Recycle Bin flows that create backend plans and enter confirmation without exposing token mechanics as a separate step
• make safe user-process port release a single guided action that creates the plan, confirms, executes, and rescans
• hide execution controls until their plans exist and focus every cleanup result after completion
• keep protected/system/service-owned port boundaries and backend token enforcement unchanged

Verification

• cargo test --all-targets (230 passed)
• cargo clippy --all-targets -- -D warnings
• npm run build
• npm run acceptance:frontend (287 selectors)
• npm run acceptance:visual -- --update-baseline (31/31)
• python scripts/run_feature_acceptance.py --mode static (68 passed, 0 failed, 1 manual)
• python scripts/run_feature_acceptance.py --mode frontend (2 passed)
• python scripts/check_repo_hygiene.py

Safety

The streamlined controls do not bypass the Rust safety contract. Port termination, cleanup, archive, and permanent Recycle Bin operations still use backend-bound plans, confirmation tokens, owner/snapshot revalidation, single-use execution, and post-operation verification.
