feat: scale the shell to the room's television

A 32" panel a few feet from the children and a 65" set across a hall want the same design at different sizes. UI_SCALE in device.conf now sets that, and nobody has to edit CSS or source to tune a room. The stylesheet and the notification config become templates carrying measurement tokens. classroom-dock resolves the stylesheet in memory at startup; classroom-notifications resolves the notification config into the session's runtime directory and execs mako on it, so the process is still just mako and everything that looks for it by name still finds it. Neither template is rewritten on disk, so an update cannot lose a room's setting and a room cannot drift from the packaged design. Dock height and the reserved strip, corner radii, padding, button size, spacing, every icon, the clock and its inset, and the notification geometry all follow the scale. Colours, translucency and the hairline borders do not: those are the design, not the size. At UI_SCALE=1.0 the rendered stylesheet is byte-identical to the one the shell used before any of this existed, which is the property worth keeping. Values outside 0.8 to 1.5 are clamped and anything that is not a number falls back to 1.0, so a typo in device.conf cannot produce an unusable classroom. Device configuration moves into a shared module, since the dock and the notification daemon now have to agree about what a setting means. Co-Authored-By: Claude Opus 5 <[email protected]>

+# border, same rounded corners, white text. Kept slightly more opaque

+# A template, not a finished config. classroom-notifications resolves the
+# bracketed measurements from UI_SCALE in device.conf and starts mako on
+# the result. At UI_SCALE=1.0 they resolve to the values they had before
