web: declutter the UI, fix date arrows, red * for bookmarked verses in reader

Daily page (index.html):
- Date arrows now step the date input client-side and dispatch its change, so
  they move relative to the CURRENT day and update the shown date (they were
  stuck one step from the initial date, computed server-side).
- Theme picker removed (theme lives only in /settings now); bookmarks link
  removed (bookmarks belong to the reader, not the daily readings).
- reader/settings nav + the download links move to a right-aligned .controls-side
  cluster; essential controls (date, lectionary, versions, parts, layout, mono)
  stay on the left. mono stops its change bubbling so it no longer refetches.

Reader (reader.html + RenderPassage): a bookmarked verse now shows a red "*"
(end of line in columns, after the verse number interlinear). Threaded a
marked set (keyed "chap:verse") through the reader render path only; the daily
RenderReadings path is untouched.

Settings (settings.html): Save button moved to the top; removed offline (dead),
width and pager (CLI/TUI-only, no web effect) -- their config values are
preserved since the handler no longer reads/zeroes them.

Footer: source/licence centred.

Web tests + full suite green both build modes.
