Replace old API endpoint with NAVI Open API for vault TVL data

[MarkChen1213866]

This PR fixes the TVL calculation precision issues in the volo-vsui adapter:

• Corrected token decimal handling for USDC, xBTC, and wBTC
• Removed unnecessary try-catch blocks
• Fixed total TVL calculation to properly sum all tokens

[llamabutler]

The adapter at projects/volo-vsui exports TVL:

sui                       0

total                    0.07881206981510985

Error while running adapter at projects/volo-vsui:

Error: 
    Please move the following keys into the chain: tvl

    We have a new adapter export specification now where tvl and other chain specific information are moved inside chain export.
    For example if your protocol is on ethereum and has tvl and pool2, the export file would look like:
    
        module.exports = {
          methodlogy: '...',
          ethereum: {
            tvl: 
            pool2:
          }
        }

please use on chain data and our sui helper functions

[MarkChen1213866]

Because of our protocol’s design, we cannot compute TVL by reading objects directly, it must be derived from event emissions. This PR follows the same approach as Haedal vaults by fetching vault metadata from API and helper to aggregate balances. Please understand this is the only feasible way to calculate TVL on our protocol, and future changes can simply adjust the packageId or API endpoint without modifying on-chain logic. Thank you for understanding🙏
