fix: complete datetime.utcnow() → datetime.now(UTC) migration

- Migrate 660+ datetime.utcnow() across 153 files to datetime.now(UTC)
- Migrate 30+ datetime.now() without UTC to datetime.now(UTC)
- Convert all 170 DateTime columns to DateTime(timezone=True)
- Add migrate_datetime_to_timestamptz() in universal_migration with SET LOCAL timezone='UTC' safety
- Remove 70+ .replace(tzinfo=None) workarounds
- Fix utcfromtimestamp → fromtimestamp(..., tz=UTC)
- Fix fromtimestamp() without tz= (system_logs, backup_service, referral_diagnostics)
- Fix fromisoformat/isoparse to ensure aware output (platega, yookassa, wata, miniapp, nalogo)
- Fix strptime() to add .replace(tzinfo=UTC) (backup_service, referral_diagnostics)
- Fix datetime.combine() to include tzinfo=UTC (remnawave_sync, traffic_monitoring)
- Fix datetime.max/datetime.min sentinels with .replace(tzinfo=UTC)
- Rename panel_datetime_to_naive_utc → panel_datetime_to_utc
- Remove DTZ003 from ruff ignore list
