settings trim: remove dead settings, upstream remnants, JSON/Clash subscriptions

Per SETTINGS-AUDIT (all three tiers approved 2026-10-23):

Dead settings:
- panelOutbound, ipLimitAllowlist (+ orphan parser job), outboundDownThreshold
- tg fake events outbound.down/outbound.up/xray.crash (no publisher in lite)
- phantom routing sub-tabs (Happ/Clash/Incy) and subJsonRules direct-rules tab
  (no backend keys); subHideSettings moved to the subscription info tab first

Upstream remnants:
- ldap* / smtp* model+schema keys, EmailNotifications orphan component
- twoFactorEnable/twoFactorToken + login-page probe (no backend handler)
- externalTrafficInform*

Newly approved removals:
- JSON subscription family (producer, routes, UA auto-detect, mux/finalmask/
  observatory) and Clash subscription family (producer, routes, UA detect)
- SubBalancer (table, service, controller, settings tab)
- subThemeDir (subscription page falls back to the built-in template)
- datepicker jalalian option (gregorian only; Persian picker removed)

JSON/Clash endpoints now 404; link-format output pinned by regression tests.
Guarded keys untouched: webListen/webPort/webBasePath/certs, tg* chain,
expireDiff/trafficDiff/tgBotProxy, subHideSettings, pageSize/tgLang.
