feat(theme+comments): runtime colour theme and COMMENTS_ENABLED switch

Browse Source 
Colour theme is configurable at runtime from two seed colours (brand + accent);
neutrals stay fixed for contrast safety. Tailwind v4 var()-based tokens let a
:root:root override recolour everything with no rebuild; the 50->950 ramps are
derived via a color-mix ladder. Config lives in the DB config table (admin UI:
Config > Farbschema, presets + custom pickers + live preview), served on the public
/event endpoint with env defaults (THEME_PRESET/PRIMARY/ACCENT), propagated live via
event-updated SSE, and cached in localStorage for a no-flash boot. The keepsake export
mirrors the same ladder in Rust so offline archives match the event theme.

COMMENTS_ENABLED (env, default true) is a boot-time kill-switch: the backend rejects
new comments with 403 and the frontend hides the comment button (feed card) and
panel/composer (lightbox). Existing comments stay in the DB, hidden, and return when
re-enabled.
