Give the tab rail its own glass bar and reserve space for it

The three tab buttons now share one frosted glass pill instead of each
floating separately, and BrowseView/RoomView reserve TAB_RAIL_CLEARANCE
of right-side padding so a full-width row or grid never renders under
it - verified against the real library, where dense rows (e.g. Conni's
82 audiobooks) previously butted right up against the rail.

Also gitignore the real (non-.example) tippen-curriculum.yml and
tippen-progress.json, matching config.yml's own privacy treatment,
since the curriculum now contains real reward paths into a personal
library.
