Note

Improves stability of the EIP-7702 gas fee token e2e and re-enables the test.

• Unskips gas-fee-tokens-eip-7702.spec.ts; adds assertion that Select a token modal is visible before validations
• Replaces inline attribute access with RowComponents.getNetworkFeeGasFeeTokenSymbolText() to read the selected token symbol
• Adds getNetworkFeeGasFeeTokenSymbolText() to RowComponents.ts
• Adds a visibility check in GasFeeTokenModal.checkAmountFiat() before reading attributes

The changes are entirely within E2E test infrastructure:

1. e2e/pages/Browser/Confirmations/RowComponents.ts: Added a new helper method getNetworkFeeGasFeeTokenSymbolText() to extract text from the gas fee token symbol element. This is a utility method only used in the gas-fee-tokens-eip-7702.spec.ts test.

2. e2e/pages/Confirmation/GasFeeTokenModal.ts: Added an assertion to check that the amount fiat element is visible before getting its attributes - this improves test stability.

3. e2e/specs/confirmations-redesigned/transactions/gas-fee-tokens-eip-7702.spec.ts:

   • Removed .skip from the test (re-enabling a previously skipped test that was causing app crashes on CI)
   • Added an assertion to check modal visibility
   • Refactored to use the new helper method

All changes are scoped to the confirmations redesigned test suite. The test file explicitly uses the SmokeConfirmationsRedesigned tag. No application code is modified, so only the relevant test tag needs to run to verify these E2E test changes work correctly.
