Thomas Hallock 3ac7b460ec feat(observer): implement shareable session observation links
Add time-limited shareable links that allow anyone to observe a student's
practice session without logging in. Links expire after 1 hour or 24 hours.

Key features:
- Parents can generate share links from the observation modal/page
- Teachers cannot create share links (API enforces parent-only)
- Shared observers are view-only (no pause/resume, no abacus control)
- Links are automatically invalidated when sessions complete
- QR code and copy buttons for easy sharing
- View count and expiration tracking for active shares

New files:
- Session observation shares DB schema and migration
- Token generation utilities (10-char base62, ~59 bits entropy)
- Share CRUD API routes
- Public observation page for token-based access
- SessionShareButton component with popover UI

Modified:
- Socket server to accept token-based observer auth
- useSessionObserver hook to support shareToken param
- Session planner to revoke shares on session end
- Observer modal/page to show share button (parents only)
