Add niche admin + public expansions + self-host Nunito font (batches 3-4)

Built via two more parallel agent workflows (read schema -> return files),
integrated + verified.

Admin: /admin/emulator (emulator_settings + emulator_texts key/value editor),
/admin/badges (give-badge via RCON), /admin/rare-values (CRUD), /admin/housekeeping
(CRUD), /admin/email-templates (CRUD), /admin/photos (moderation).
Public: /rares (+[category]), /leaderboard (credits/diamonds/duckets),
/guilds (+[id] members), /redeem (voucher -> sendCurrency).
Expanded: /u/[username] now shows badges + photos + guestbook (post form);
/news/[slug] now shows reactions + comments (comment form). Reactions tallied
in JS (Prisma groupBy typing avoided).
Self-hosted Nunito via next/font/google wired to --font-nunito (the atom theme
font, no runtime external fetch). Header + admin nav extended.

Verified: tsc exit 0, vitest 48/48, next build exit 0.
