Add per-tab tutorials, profile expand/collapse, and fix card animation

- Add sub-tutorials for Dashboard, Targets, Sources, and Profiles tabs
  with ? trigger buttons, en/ru/zh translations, and hidden-ancestor
  skip via offsetParent check
- Add expand/collapse all buttons to Profiles tab toolbar
- Move dashboard poll slider from section header to toolbar
- Fix cardEnter animation forcing opacity:1 on disabled profile cards
- Use data-card-section selectors instead of data-cs-toggle to avoid
  z-index misalignment during tutorial spotlight
- Add tutorial sync convention to CLAUDE.md
