Fix CI test failures

[sergeychernyshev]

This PR resolves the test failures observed in CI and local environments, and refines the admin verification logic.

Changes:

• Architecture: Removed email-based admin verification. Admins are now verified strictly by their User Durable Object IDs.
• Local Dev: Migrated local development configuration to wrangler.local.jsonc (ignored by git) and updated .gitignore.
• Developer Scripts: Updated package.json scripts (dev, start, cf-typegen) to use the new wrangler.local.jsonc configuration file.
• API Fix: Updated the admin impersonate endpoint to accept both user_id and userId. The tests were sending userId, causing 400 Bad Request errors.
• Improved isAdmin Robustness: Refactored the isAdmin function to consistently handle various user object structures and removed reliance on emails or provider-specific IDs.
• System Index Update: Updated SystemDO.listUsers to reflect the new admin verification logic (removing email/provider checks).
• Test Resilience: Updated wrangler.test.jsonc to use only admin ID in ADMIN_IDS.
• Refactoring: Cleaned up handleMeImage to use getUserFromSession, removing duplicate session handling logic.
• Bug Fix: Added an explicit 404 response for unhandled admin /api/ paths. This prevents falling through to static asset fetching, which could cause TypeError when the request body was already consumed.

Closes #72
