fix: Update rollback mechanism to use consistent profileService approach

[codeunia-dev]

• Replace create_oauth_profile RPC calls with profileService.getProfile() in auth callback
• Ensure consistent profile creation across OAuth flow and complete-profile page
• Maintain auto ID generation (CodeUnia ID and username generation)
• Fix rollback mechanism to use same approach as complete-profile page
• Remove dependency on potentially missing create_oauth_profile RPC function
• Add proper error handling for profile creation failures
• Ensure graceful fallback to complete-profile page on any errors

This ensures the rollback mechanism works consistently and uses the same profileService approach that handles auto ID generation properly.

Walkthrough

Removes the .env.example template file. Updates app/auth/callback/page.tsx to replace direct RPC-based profile creation with a service-based profileService.getProfile check across all OAuth flow branches, preserving existing redirect logic to /complete-profile and logging behavior.

• feat: Add OAuth profile completion flow #241 — Also modifies app/auth/callback/page.tsx around missing/incomplete profile handling during OAuth callback, using RPC-based checks and redirects to complete-profile.

Poem

A hop, a bop, through auth we glide,
Profiles checked by service-side.
The env file’s gone—less clutter to see,
Yet flows still bound for /complete-profile, whee!
Thump-thump logs, then onward we go—
Ears up high for the redirect show. 🐇✨
