Fly.io's existing connection and execution APIs were missing from the frontend. This adds a Fly.io card to Integrations with organization/token inputs, Verify connection, save, and disconnect actions, plus Fly.io execution selection in the job editor.

Users can choose a public VM image, region, and size, save those settings as a reusable execution configuration, and select a ChatGPT model account for Codex jobs. Unsaved VM settings block job submission, and editing preserves portable integration and model account selections.

Validation:

• Full npm test passed with Node 24.12.0 and npm 11.19.0 against an isolated local PostgreSQL container.
• Added mocked browser E2E tests for verification rejection/recovery, token clearing, disconnecting, and mobile agent/code job creation with VM settings preserved on reload.
• Backend: 697 passed / 5 skipped; browser unit suite: 108 passed / 1 skipped; critical Playwright suite: 7 passed; credential proxy suite: 79 passed.
• No Fly.io requests were made and no Fly.io resources were created.
