Top 5 Code Reduction Opportunities Implementation

Identify top 5 opportunities to massively reduce the amount of code (lines of code) in any part of the repo: - Similar functionality that can be unified and reused - Code that has been valuable but no more - A front end component or a group of them duplicate another component/page functionality. Use the most modern and nice looking - etc. Now implement them :)

Shipped 4 unifications (InlineSelect, ForgeSetup table, tools daemon_busy+hermetic env, ProjectTextCell); 5th (useSubmit adoption) investigated and rejected after the review lane caught a contract break. Net LOC ≈ 0: repo had no large duplication left (fleet_session census, contract-test anchors). Quick gate green; PR #7693 queued to the merge lane. Visual check done: task Details, automation Endpoint, project Governance render unchanged. Memory: used mem-32769; proposed 1 qa.
