Polish sticky headers, Custom View, docs page and dialogs

- Status tables: the whole header (column names + filters) sticks as one
  block, tucked 1px under the group header, so no gap can open between
  the rows; offsets use fractional heights
- Phones/tablets: the filter panel sticks under the group header too, and
  is opaque and compact (three filters per row on phones)
- Custom View: fix the group header being pushed over the column header
  (it lives inside the view's own scroll box); the column header now pins
  to the top of that box on desktop, and the header strip sticks on phones
- All Devices: group title is "All Devices (N)" instead of "Missing
  Software", matching the page title count
- Documentation fits the window on desktop: only the article list and the
  article scroll; placeholder no longer says "from the left"
- Dialogs sit above the terminal dock so it can't cover their last rows;
  page bottom padding follows the dock's measured height
