feat: fetch shielded balances on transfer

[euharrison]

This PR resolves most of the current issues related to the shielded balance

• Re-run the shielded sync and the shielded balance after any successful transfer.
• The balance is now saved on local storage and we can provide the last cached value
• Added a shielded sync indicator on the sidebar that shows the percentage of the shielded sync on any Masp page and the Overview
• Also, update the indicator text when the shielded sync is converting assets, which currently takes a longer time and we don't have a progress indicator on the sdk side
• Fix the dollar value considering the NAM as zero until it's available on osmosis api.
• Add a 2h timeout for transfers that do not completed and aren't available on chain for whatever reason

Very good improvements! But I still feel we would need something better to handle the masp updates. Like an optmistic updates. I'll think of a solution too
