P1-P3 admin cleanup: rank guard, SSRF guard, count caching, dead code removal, pagination rewrite

- P1: new src/lib/admin/rank-guard.ts with tryGuardRank/guardRank + RankGuardTarget/Result; extracted from users.ts; applied to admin-bans (create/lift + rank redirect) and admin-badges (caps + rank guard + error surfacing); import-url-safety.ts SSRF guard wired into clone save+icon fetch; logAudit await in help-tickets; antiddos mutations SETTINGS_EDIT; markAllAlertsRead NOTIFICATIONS_EDIT; rankError/saveError in all 25 message files; tests rew/new for bans/badges/rank-guard/import-url-safety

- P2: ticket-inbox merged pagination reworked to single UNION ALL SQL with LIMIT/OFFSET (avoids O(offset) materialization); getCachedAdminCount with cacheFiltered option applied to devops/errors/photos/items/guilds/help-tickets/moderation pages; admin-theme catches→?error=1+banner+25 locales; logger in silent catches (rare-values/writeable-boxes); catalog-items-loader CAST→plain equality; count caching helper extended with opt-in cacheFiltered

- P3: removed dead modules is-staff/notice/recent-furni-resync/log-filters plus load-user-sanctions/user-sanction-timeline; removed orphaned CATALOG_PAGE_COLUMNS re-export; removed getFurniIconUrl from studio-furni-icons
