chore: commit pre-existing untracked work + finish archived-doc notes

Commits work that predated this session and was sitting untracked:
qualitative sell strategy module (src/quant_engine), the t20 outcome
ledger cron workflow, the QuantEngine masterpiece roadmap doc, a WBS
execution yaml, and shared Razor Pages partials (page header, delete
confirm modal) with their view models. Verified these build clean
(0 errors, 0 warnings) before committing.

Also includes the "ARCHIVED" header notes on 6 docs archived in the
previous commit - the git-mv landed there, but the note text itself
was missed from that commit's staged file list.
