E2E Test Selection:
The changes remove the disableUpgrade: true flag from the addTransactionBatch call in PredictController.ts. This is a focused change that affects how prediction market transactions are processed - specifically enabling transaction upgrades that were previously disabled.

The PredictController is a Phase 6 (business logic) controller that handles Polymarket prediction market integration. The change is isolated to this feature domain.

Tag selection rationale:

1. SmokePredictions - Directly tests the Polymarket prediction market integration including opening positions, cashing out, and claiming winnings - all of which involve transactions that would be affected by this change.
2. SmokeConfirmations - Per tag description guidance, when selecting SmokePredictions, also select SmokeConfirmations since opening/closing positions are on-chain transactions that go through the confirmation flow.
3. SmokeWalletPlatform - Per tag description guidance, Predictions is a section inside the Trending tab, so changes to Predictions views affect this tag.

The test file change (PredictController.test.ts) simply updates the test expectations to match the code change, removing the same flag from the expected call parameters.

Performance Test Selection:
The change affects transaction processing in the PredictController, specifically how transaction batches are submitted for prediction market operations. The @PerformancePredict tag covers prediction market flows including deposit flows and balance display, which could be impacted by changes to transaction upgrade behavior. While the change is small (removing a flag), it could affect transaction processing timing and performance characteristics.
