feat(uload): sync_changes integration, Stripe checkout, docs update

Sync integration:
- Redirect service reads links from mana-sync's sync_changes table
- Analytics service queries clicks from sync_changes
- Click tracking writes to sync_changes (visible to all clients)
- Public profile reads from sync_changes
- Server DB points to mana_sync database (not separate uload DB)
- Removed uload-database dependency from server

Stripe:
- Real Stripe checkout session creation (monthly/yearly)
- Webhook handler with signature verification
- Webhook route bypasses JWT auth

Documentation:
- Root CLAUDE.md: added uload to project table, dev commands, local-first list
- mana-sync CLAUDE.md: added uLoad, Taktik, Calc to connected apps
