feat: Implement smart waiting utilities for improved page readiness and element detection

- Added `waitForPageReady` and `waitForElementSmart` functions to replace fixed timeouts with intelligent checks.
- Updated various parts of the codebase to utilize the new smart wait functions, enhancing performance and reliability.
- Improved logging for page readiness and element detection.
- Refactored login and browser functions to reduce unnecessary waits and enhance user experience.
- Fixed selector for MORE_ACTIVITIES to avoid strict mode violations.
- Added unit tests for smart wait utilities to ensure functionality and performance.
