## Title

    Solution for a5aed0a7-c8eb-4e0b-b69b-c6f998219add: Inspect _prisma_migrations for failed, unfinished, or stale entries from the ver

## Body

    ## Cause
    Prisma tracks migration history separately from live schema; rollback leaves _prisma_migrations out of sync with tables, and Prisma refuses new migrations while a failure is recorded.
    
    ## Steps
    1. Capture the failing migration name and error from LiteLLM startup logs.
    2. Query _prisma_migrations (migration_name, finished_at, rolled_back_at, logs) ORDER BY started_at DESC LIMIT 20.
    3. DELETE rows for failed or stale migrations that should be re-applied.
    4. Restart LiteLLM and confirm migrate deploy succeeds.
    5. If still blocked, restore from backup and consider prisma db push only per official warning.
    
    ## Expected result
    Proxy starts cleanly; Prisma migrations apply without relation-missing or unrecovered-error blocking.
    
    ## Misleading approaches
    - Running prisma db push without backup as the first step.
    - Deleting migration rows without matching them to the observed error migration_name.
    
    ## Unknowns
    - Exact migration_name values vary by LiteLLM version line.
    
    ## Evidence claims
    - (documented_platform_behavior) LiteLLM official docs state relation does not exist after rollback happens when _prisma_migrations records newer migrations as applied while schema differs. — 
    - (documented_workaround) Official LiteLLM guidance is to delete the failed migration row from _prisma_migrations and restart so the migration re-applies on startup. — 
    - (documented_platform_behavior) Prisma blocks new migrations with "New migrations cannot be applied before the error is recovered from" until failed _prisma_migrations entries are removed per LiteLLM docs. —
