feat: Refactor settings pages to preload graphql queries while navigating

[cephalization]

Also fixes a few bugs:

• Models page is now powered by a collection query. This allows for more consistent and efficient updates after cloning, updating, or deleting models
• AI Provider credentials settings page now lets you edit credentials. Previously the dialog would close when you type any character when editing provider credentials
• Data retention policy connections are refactored for simplicity and less prop drilling

---

Note

Switches generativeModels to a paginated connection and refactors settings pages to use preloaded Relay loaders with connection-based updates.

• GraphQL/API
  • Add GenerativeModelConnection/GenerativeModelEdge; change Query.generativeModels to a paginated connection with args.
  • Server generative_models now returns a Connection (supports first/last/after/before).
• Settings – Models
  • Convert ModelsTable to use Relay connection (edges.node) with @connection and @refetchable.
  • Update create/clone/delete mutations to use @prependNode/@deleteEdge with connectionId (no route revalidation).
  • Page uses preloaded loader; adds debounced search and revamped Select/ListBox usage.
• Settings – Data Retention
  • Simplify connections by deriving connectionId from client:root; remove prop drilling.
  • Page and loader migrated to preloaded queries.
• Settings – Annotations
  • Switch to preloaded + refetchable fragment; mutations refetch via fragment instead of route revalidation.
• Settings – AI Providers
  • Extract ProviderCredentialsStatus; fixes editing UX and default input handling.
• Settings – Prompts
  • Add settingsPromptsPageLoader and wire route loader; improve delete label error handling (toast).
• Misc
  • General migration to loadQuery/usePreloadedQuery; remove unnecessary useEffect disposals.
  • ListBox refactor to pass ref prop directly.

Bug: Schema Mismatch Causes UI Update Delay

The @prependNode directive in NewModelButton.tsx has edgeTypeName: "GenerativeModel". This mismatch with the schema's GenerativeModelEdge (used correctly in CloneModelButton.tsx) means new models don't appear in the UI immediately.

Bug: Credential Check Fails on Empty Strings

The credential check logic now uses !! instead of !== undefined, which causes intentionally empty string environment variables to be treated as "not set." This can incorrectly report providers as "not configured" when an empty string is a valid or desired credential value.
