Condense Operations sidebar: remove 5 items, tighten padding

Layer 1 — relocate off nav:
  Shop Display + Shop Mobile → Jobs page header (split dropdown on Blank Work Order)
  Powder Insights → Inventory page header button

Layer 2 — remove orphan section headers:
  "Main Menu" (only had Dashboard under it)
  "Reports" (only had Reports link under it)

Layer 3 — CSS density:
  nav-link padding 0.75rem → 0.55rem vertical
  nav-section-title padding 1rem/0.5rem → 0.65rem/0.3rem

Operations mode: 27 elements → 22. Scrollbar eliminated on standard screens.
