fix(frontend): Fix flaky agent-activity tests by targeting correct agent (#11790)

This PR fixes flaky agent-activity Playwright tests that were failing
intermittently in CI.

Closes #11789

### Changes 🏗️

- **Navigate to specific agent by name**: Replace
`LibraryPage.clickFirstAgent(page)` with
`LibraryPage.navigateToAgentByName(page, "Test Agent")` to ensure we're
testing the correct agent rather than relying on the first agent in the
list
- **Add retry mechanism for async data loading**: Replace direct
visibility check with `expect(...).toPass({ timeout: 15000 })` pattern
to properly handle asynchronous agent data fetching
- **Increase timeout**: Extended timeout from 8000ms to 15000ms to
accommodate slower CI environments
