Android Feedback + About tabs (Compose, Material 3)

Add a bottom navigation with Feedback and About tabs to an existing Compose app, in the Tertiary Infotech house style. Drop the content tab(s) you already have alongside them.

• Feedback tab: Title + Message text fields and a Send via WhatsApp button that opens https://wa.me/6588666375?text=<urlencoded title + message>.
• About tab: an app card (name + about text), a Developer card ("Tertiary Infotech Academy Pte. Ltd." + tertiaryinfotech.com link), an optional Data source card (link to the official data source — required if surfacing government data; see android-app-submission §8), and a Version row from BuildConfig.
