Refine wallet synchronization warning for enhanced clarity #27262

This pull request updates the wallet synchronization warning text to provide a clearer and more concise message to users. The original text was somewhat clumsy and suffered from grammatical issues, which could lead to confusion. The changes made are as follows:

• Replace the original warning text with a more concise and grammatically correct version.
• Clarify that transactions using bitcoin from unseen transactions due to ongoing synchronization will be rejected by the network.

These changes aim to improve user experience by providing clearer information about potential issues related to wallet synchronization.

Old text: "Recent transactions may not yet be visible, and therefore your wallet's balance might be incorrect. This information will be correct once your wallet has finished synchronizing with the bitcoin network, as detailed below. Attempting to spend bitcoins that are affected by not-yet-displayed transactions will not be accepted by the network."

New text: "Wallet balance may be inaccurate during synchronization, as recent transactions may still be loading (details below). Caution: Transactions using bitcoin from unseen transactions (due to ongoing synchronization) will be rejected by the network."

I'm not sure your changes are actually an improvement. However, you can drop all of the changes you've made to the .ts files. You've also opened this in the wrong repository. It's a GUI change.

It's mostly motivated by the poor grammar of the current wording. We should at least make it grammatically correct, shouldn't we? Are you objecting to it now being so few words in the first part? I can leave that unchanged if so.
