Thanks!

@Praneetha15 Could you explain why the tsconfig.json file is included in this PR?

[Praneetha15]

@pierrelstan I reverted apps/native/tsconfig.json to exactly match upstream main so this PR no longer includes any tsconfig changes. I’ve also merged the latest changes from upstream/main into this branch to stay up to date. The PR now only contains the intended wallet UI updates.

[pierrelstan]

Could you squash the last three commits into one using git rebase -i HEAD~(any number) and then rebase onto the main branch using git rebase origin/main? This ensures the code is up-to-date with the main branch and has a clean, linear history.

[Praneetha15]

I noticed some upstream changes (workflow, .gitignore, bdd files) appeared in this branch after syncing with main. I can remove those and make the PR only contains my "native wallet" updates (apps/native/app/(tabs)/wallet/index.tsx and apps/native/constants/Colors.ts). Would you prefer I do that, or is the current diff acceptable?

@Praneetha15 The PR should focus only on the Wallet screen changes. Please exclude any unrelated changes to keep it clean.
