Implement ZeroDB Durable Object for Centralized Database Access

Description

This PR introduces a new ZeroDB Durable Object to centralize database operations. Instead of creating multiple database connections throughout the application, database operations are now routed through this Durable Object. This approach provides better connection management and a more organized data access layer.

The implementation:

1. Creates a new ZeroDB class that encapsulates database operations
2. Refactors existing code to use the Durable Object instead of direct database access
3. Adds logging for database connection creation
4. Updates Wrangler configuration to register the new Durable Object

Type of Change

• ⚡ Performance improvement
• 🔒 Security enhancement

Areas Affected

• Data Storage/Management
• Authentication/Authorization
• Deployment/Infrastructure

Testing Done

• Manual testing performed

Security Considerations

• No sensitive data is exposed
• Authentication checks are in place

Checklist

• I have performed a self-review of my code
• My changes generate no new warnings

Additional Notes

This change should improve database connection management and reduce the number of connections being created, which should help with performance and resource utilization.

Walkthrough

This update refactors server-side database access by introducing a centralized ZeroDB Durable Object. All modules now interact with the database through this object using high-level methods, replacing direct ORM queries. The change also updates configuration to bind the new durable object, and adjusts routing and middleware to use the new abstraction.

Poem

🐇
A hop, a leap, a bounding spree,
Now all our data flows through ZeroDB!
No more scattered queries, no more ORM fright—
Durable Objects keep our data tight.
With one big hop, the code is clean,
The server’s happier than it’s ever been!
— Your friendly coding rabbit 🥕
