fix(backend): lower PlatformCostLog DataError to warning during schema mismatch

The autogpt-database-manager pod can run a stale Prisma client immediately
after a schema migration (e.g. rolling deploy of PR #12696 that added
PlatformCostLog). This caused every copilot token-tracking write to raise
prisma.errors.DataError ('userId'/'metadata' field not found), which was
caught by logger.exception() — firing Sentry events at ERROR level.

Catch DataError specifically in both log_platform_cost_safe (platform_cost.py)
and the _safe_log closure in token_tracking.py, and demote to WARNING so
Sentry is not spammed during deploy windows. All other exceptions still
escalate to ERROR/Sentry as before.
