polish(ui): full-system layout audit, header titles for all routes, dialog title truncation

- headless DOM audit (Edge dump, 1440/390 x 10 routes): no real horizontal page overflow on any screen size; timeline bleed & drawer offsets are intentional and verified benign
- header now labels profile/resume/assessment/admin routes (was blank h1 on those pages)
- dialog header truncates long titles instead of pushing controls out
- page containers audited for consistent rhythm (1080/1280/880 widths share identical paddings)
- www rebuilt, temp instrumentation removed
