Fix splash screen page indicators positioning and state

[Copilot]

Splash screen 2's TabLayout indicator was misaligned (left-constrained instead of centered) and lacked an ID. Neither splash screen indicated which page was active.

Layout changes:

• Centered TabLayout in Splash2 by adding end constraint and removing start margin
• Added android:id="@+id/tabLayout" to Splash2's TabLayout
• Added explicit TabItems to both splash screens (2 tabs each)
• Aligned nextArrow2 to TabLayout (matching Splash1 pattern)
• Standardized bottom margins to 32dp across both screens

Activity changes:

• Splash1Activity selects first tab on load
• Splash2Activity selects second tab on load

// Splash1Activity.java
TabLayout tabLayout = findViewById(R.id.tabLayout);
TabLayout.Tab tab = tabLayout.getTabAt(0);  // First page
if (tab != null) tab.select();

// Splash2Activity.java  
TabLayout tabLayout = findViewById(R.id.tabLayout);
TabLayout.Tab tab = tabLayout.getTabAt(1);  // Second page
if (tab != null) tab.select();

Both screens now show centered page indicators with the active page highlighted.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

I want to fix splash screen indicator on the bottom of splash 2 and I'll add it to splash 1 too
