fix(settings/analytics): canonical /en/, precise anchor navigation, scope card copy

Canonical URL fixes (parity with trump/macro/kol done earlier):
- analytics/page.tsx: canonical was `${siteUrl}/${locale}/analytics` → /en/
- settings/page.tsx:  canonical was `${siteUrl}/${locale}/settings`  → /en/

Settings scope card anchor navigation:
- Three scope cards ('Trump Signal ↓', 'Macro Vibes ↓', 'Global ↓') all
  pointed to #bot-config — same destination, no differentiation. Renamed:
  #config-trump / #config-macro / #config-global.
- Added matching id='config-trump/macro/global' to the three sections in
  BotConfigPanel so the anchors actually land at the right section.
- Removed misleading 'tab' wording ('Trump Signal tab ↓') — BotConfigPanel
  is not a tab component; it's a single-page vertical form. Copy now reads
  'Configure Trump ↓' etc.
- SystemControl already links to settings#bot-config which still resolves
  (the outer #bot-config wrapper div in SettingsClient is unchanged).

tsc + next build clean.
