feat(nov): reading-view theme layer with palettes and font sizing

EPUB reading prefs were scattered: a hardcoded Merriweather/180 font-remap in calibredb-epub-config's nov hook, no color control (the old sepia foreground had been stripped), and a frame-global EBook fontaine preset as the only way to size up. That preset resized the font in every buffer in the frame, not just the book.

I pulled the reading view into its own layer, modules/nov-reading.el, on top of stock nov (no fork). It owns three things, all buffer-local: a reading palette (sepia/dark/light, each a face the dupre theme owns, sepia the default), the serif typography (family plus a defcustom base height replacing the hardcoded 180), and page font sizing (+/- bump the size live, = resets to the base). Width moves to { }. calibredb-epub-config keeps the library and width/centering layout. Its nov hook now calls into the layer.

The three palette faces register as a nov-reading app in theme-studio (face_data.py), so they're tunable there like any other app. I dropped the EBook fontaine preset, since reading size is buffer-local now.
