Close remaining web gaps: rich profile, login history, lightbox/slider, flash client, admin chatlog/DJ/chart/WYSIWYG, niche API

- Rich profile (/u/[username]): wallet (credits/duckets/diamonds), friends
  grid (messenger_friendships), and owned rooms sections.
- Login history: new website_login_logs table (model + migration 0007),
  recorded on every successful sign-in (ip + user-agent), surfaced on a new
  /settings/sessions page (with failed-attempt list from failed_logins).
- Photos lightbox + home article slider (client components, no Swiper dep).
- /client/flash launcher (SSO ticket like the Nitro page).
- Admin: private chatlogs section in /admin/logs, /admin/radio/moderation
  (shout moderation), a "users by rank" inline bar chart on the dashboard,
  and a TinyMCE rich-text editor on the article admin forms.
- Niche API: /api/values/[id], /api/guilds(+/[id]), /api/radio/auto-play.

Verified live (prod, amx_test): login recorded → /settings/sessions shows
it with device; profile renders wallet/friends/rooms; dashboard chart +
private-chat logs + /client/flash + /api/guilds all OK. Reverted test data.
