chore: cleanup dead props, deps, dirs, and stale comments

- Remove empty dirs: modules/mana/, modules/subscription/, and 7
  empty route dirs (spiral, profile, themes, help, apps, mana, credits)
- Remove @mana/subscriptions from web app dependencies (never imported)
- PillNavigation: drop settingsHref, manaHref, allAppsHref/allAppsLabel
  props + their link-builder blocks (none are passed anymore; all system
  pages route via /?app=<id> deep-links now)
- Update layout comment to reflect current architecture
