fix: Wi-Fi Selection on Calibre Library launch (#313)

Browse Source 
## Summary

* **What is the goal of this PR?** 
Fixes the Wi-Fi connection issue when launching the Calibre Library
(OPDS browser). The previous implementation always attempted to connect
using the first saved WiFi credential, which caused connection failures
when users were in locations where only other saved networks (not the
first one) were available. Now, the activity launches a WiFi selection
screen allowing users to choose from available networks.

* **What changes are included?**

## Additional Context
**Bug Fixed**: Previously, the code used `credentials[0]` (always the
first saved WiFi), so users in areas with only their secondary/tertiary
saved networks available could never connect.
