fix(e2e): fix textExists and Settings navigation on Linux

- Use XPath in textExists on tauri-driver instead of innerText
  (innerText misses off-screen/scrollable content on webkit2gtk)
- Use waitForText with timeout in navigateToBilling instead of
  non-blocking textExists check
- Make /telegram/me assertion non-fatal in performFullLogin
  (app may call /settings instead)
