Subject: [PATCH] Upgrade asset pipeline to Sprockets 4 (sass-rails 5 -> 6)

sass-rails 5.1.0 capped sprockets at < 4.0; bumping it to ~> 6.0 lifts the
cap and moves the app onto Sprockets 4.2.2 (sass-rails 6 delegates SCSS
compilation to sassc-rails). Both lockfiles updated.

Kept the update scoped: used --conservative so rack stays at 2.2.23 rather
than being dragged to 3.x as collateral. The app/assets/config/manifest.js
Sprockets 4 requires was already present.

This unblocks two follow-ups that Sprockets 3.x's unconditional CoffeeScript
engine was blocking: removing coffee-rails and swapping uglifier -> terser.

Verified: boots on Sprockets 4.2.2, assets:precompile succeeds (application
js/css + pdf.css, including the font-awesome and fastruby/styleguide
imports), and the full test suite passes (16 runs, 52 assertions, 0
failures).
