E2E Test Selection:
This PR is a test file reorganization that moves E2E test spec files from e2e/specs/ to a new tests/smoke/confirmations/ directory structure. All 22 changed files are E2E test files related to confirmations functionality:

1. Send tests: send-native-token, send-erc20-token, send-btc-token, send-solana-token, send-tron-token
2. Signature tests: signatures, signatures-typed, alert-system
3. Transaction tests: contract-deployment, contract-interaction, dapp-initiated-transfer, per-dapp-selected-network, transaction-pay
4. Token approve tests: approve, increase-allowance, set-approval-for-all
5. EIP-7702 tests: batch-transaction, gas-fee-tokens-eip-7702, gas-fee-tokens-eip-7702-sponsored
6. Regression test: new-networks-signatures

All these tests are tagged with SmokeConfirmations (or RegressionConfirmations). The changes are purely structural:

• File relocations from e2e/specs/ to tests/smoke/confirmations/
• Import path updates to reflect new directory structure
• File path reference updates in test fixtures (e.g., withDelegatorContracts.json path)

No application code or test logic is modified. Running SmokeConfirmations is essential to verify that:

1. All import paths are correctly updated
2. File references in test fixtures work correctly
3. The test infrastructure still functions after the reorganization

This is a medium risk change because incorrect import paths could break tests, but the scope is limited to test infrastructure only.

Performance Test Selection:
This PR only reorganizes E2E test files by moving them to a new directory structure and updating import paths. No application code is changed, no UI components are modified, and no performance-critical code paths are affected. The changes are purely structural test infrastructure changes that do not impact app performance in any way.
