Release 0.3.0

Simple billing

Add billing CRDs and controller logic for handling billing events and cluster billing status updates. This includes:

1. New CRDs for Billing and BillingEvent resources
2. Controller logic to:
   • Track cluster billing status
   • Generate periodic billing events
   • Process billing events to update balances
3. Configuration options to enable/disable billing controller
4. Dependency updates and cleanup

Current Issues:

• You can delete billing and lose the entire balance, including both positive and negative balances.
• When deleting all fleet workspaces, the user loses the fleet UI, resulting in the inability to create or delete fleet workspaces anymore.
