CP-12596 - Core mobile crashes when trying to stake

[bogdandobritoiu]

Description

Ticket: CP-12696

• Memoized headerTitle and headerBackground inside useFadingHeaderNavigation as well as cleanup on useFocusEffect. Google play console crashes reports that the header rerendering or out of view is causing this crash.
• Added freezeOnBlur to modals and secondaryModals

Gemini crash report from Google Play Console
The crash indicates an IllegalStateException occurring because a View is being added to a parent ViewGroup when it already has an existing parent. This typically means a view object, specifically one managed by com.swmansion.rnscreens.ScreenStackHeaderConfig for the screen's header, was attempted to be attached to the view hierarchy without first being properly removed from its previous parent. This issue is observed during an onUpdate or onAttachedToWindow lifecycle event within the rnscreens library, suggesting a problem with how header views are being managed or re-rendered in the React Native application's native component layer.

Testing

Dev Testing (if applicable)

iOS - 6706
Android - 6707

Current behavior after test is finished
page stalls for 2-3 minutes and then crashes.

1. activate fuji (reported on mainnet, can repro on fuji)
2. navigate to the stake flow in core mobile
3. start a stake and enter an amount
4. set a CUSTOM DATE (do not pick one of the auto populated ones, open the custom option and select from a calendar)
5. continue to advanced set up
6. specify filter amounts and continue
7. select a node to stake to
8. review details and confirm

Expected behavior
Staking finishes as expected and it takes less that 2-3 minutes to finish the last step
