fix(studio): handle undefined connectionStringPooler in connect sheet

[alaister]

Follow-up to #44471. Fixes Sentry error: can't access property "ipv4SupportedForDedicatedPooler", g is undefined.

connectionStringPooler can be undefined when the databases query hasn't resolved yet (returns [] by default, so the lookup object is empty). Added optional chaining + explicit typing.

To test

• Open the connect sheet on any project — should render without errors
• Check that IPv4 status panel still displays correctly once loaded

Summary by CodeRabbit

• Refactor
  • Improved type safety and robustness in connection pooler configuration handling for more reliable IPv4 capability detection.

📝 Walkthrough

Walkthrough

Updated DirectConnectionContent component to add explicit type annotation for connectionStringPooler as ConnectionStringPooler | undefined and replaced unsafe property access with optional chaining to safely handle potentially missing pooler data.

Changes

Cohort / File(s)	Summary
Type Safety Enhancement apps/studio/components/interfaces/ConnectSheet/content/steps/direct-connection/content.tsx	Added explicit type annotation for connectionStringPooler variable; replaced direct property access with optional chaining (?.) and nullish coalescing (??) for safer handling of undefined pooler data; expanded imports to include ConnectionStringPooler type.
