Fixes #6482

What changes did you make and why?

Problem
On the Nearby screen, the placeholder from nearby_search_hint ("Bridge, museum, hotel") was not visible in the SearchView.

Approach

• Runtime enforcement in NearbyParentFragment.initNearbyFilter()

  • Force-set queryHint = getString(R.string.nearby_search_hint).
  • Ensure the SearchView is de-iconified and unfocused so the hint can render (setIconifiedByDefault(false), clearFocus()).
  • Access the internal EditText (androidx.appcompat.R.id.search_src_text) and set the hint + hint text color as a fallback for OEM differences:
    • searchEditText.hint = getString(R.string.nearby_search_hint)
    • searchEditText.setHintTextColor(ContextCompat.getColor(requireContext(), R.color.white))
  • Wrapped with try/catch + Timber.e for graceful degradation if internals differ.

• Layout

  • In filter_search_view_layout.xml: keep android:queryHint="@string/nearby_search_hint", android:iconifiedByDefault="false", app:theme="@style/WhiteSearchBarTheme", and search icon setup to improve consistency across devices.
  • In styles.xml: add WhiteSearchBarTheme (inherits DarkAppTheme) with white controls to guarantee hint contrast on dark backgrounds.

• Repository hygiene

  • Rebased on the latest upstream main before making changes.
  • Removed obsolete leftover code from a prior attempt to fix [Bug]: the string "Bridge, museum, hotel" is not visible #6482 to reduce confusion and ensure a clean diff.

Result
The placeholder "Bridge, museum, hotel" reliably appears when the field is empty, improving first-use discoverability in Nearby.
