Task: Integrate dashboard dynamic nice scale

Identity

Integrate feature commit 6e212b3 from task 20260902-dashboard-nice-scale-d8c31a into current main after the password-flow integration.
Preserve the newly integrated non-empty-only password behavior while applying only the dashboard dynamic-scale source, cache, test, and task-record changes.
Record the source commit in canonical current state and run the complete repository/project-document verification gates.

Keep the accepted row-as-bar leadership ranking and operation-count semantics; add readable per-ranking headroom using the verified 1 / 2 / 5 / 10 dynamic scale.
Preserve password-flow changes, account roles, task ownership, route authorization, leadership access, business-safe copy, ranking order, and drill-through.
Do not promote any new product, authorization, API, or data-model decision; the source task has no canonical promotion candidates.
Do not restart, deploy, mutate runtime data, access ERP, or send data externally. The running service may serve the updated static assets directly after integration.

Verified source feature commit 6e212b3 and its task record, including the absence of promotion candidates or semantic conflicts.
Cherry-picked the feature onto the post-password-flow main baseline as commit 63b387f; Git merged the overlapping platform and test files without conflict.
Preserved the integrated non-empty-only password behavior and removed-first-login flow while adding only the dashboard dynamic scale, cache version, focused tests, and source task record.
Recorded the integrated source and behavior in canonical current state.
Confirmed the running 8786 service serves dashboard-nice-scale-1 assets and the integrated operationsDashboardRankScale implementation directly; no service restart was required or performed.

node --check LianSyn-platform/app.js: passed.
Focused account/dashboard regression: 8/8 passed on integrated main.
node --run check:repo: 10/10 passed.
node --run check: passed.
node --run test:control-plane: 153/153 passed.
node --run test:legacy: 260/260 passed, including the integrated password-form coverage.
node --run build: passed.
git diff --check: passed.
Local HTTP verification against http://127.0.0.1:8786/ confirmed both asset URLs use 20260902-dashboard-nice-scale-1; the served JavaScript contains the dynamic-scale helper and exact-boundary headroom branch.
Source-task isolated browser verification rendered 43 at 86% on a 50 scale and 359 at 89.75% on a 400 scale, with descending order and task-type click-through intact.

Refresh the already-open dashboard tab to load the new cache-busted assets if it was opened before commit 63b387f.

None. The integrated change is a presentation refinement within the accepted leadership-dashboard behavior.
