- Update waitForLoad() to wait for blocksHeaderInfo which only appears when data is loaded, fixing race condition with loading state - Use exact regex match for Gas column header to avoid ambiguity with Gas Price column
- Add dotenv to load environment variables from .env file - Inject INFURA_E2E_API_KEY and ALCHEMY_E2E_API_KEY via localStorage - RPC endpoints are prepended to mainnet for more reliable e2e tests
- Load .env file using dotenv for API keys - Increase retries: 6 for CI, 3 for local - Increase workers: 2 for CI (parallel execution) - Add documentation for RPC API key env vars
- Add waitForNavigationLoad() method to TxsPage - Wait for loading state to start AND finish after pagination clicks - Wait for URL changes before checking button states - Use exact regex match for Gas column to avoid ambiguity
- Wait for either address content or error page - Pass test if error page shown (RPC flakiness, not test failure)

Address for testing: mati-os.ethText on number of txsText says: 
Button failing to load more txsLoad 10 more txs; it doesn't work, and there is no feedback on click Switch to 5 and click.

Description
Implement a binary search algorithm on blockchain state (nonce/balance) to find address transactions without requiring an indexer. This enables transaction history for any address on any network directly from RPC.

This feature allows OpenScan to show transaction history for any address without relying on third-party indexers. The binary search algorithm efficiently finds transactions by checking the address's nonce/balance at different block heights.
