feat: support vault fee data fetching + influence vault fee handling

[okjintao]

Summary

• support fetching vault fees for any vaults
• we should consider implications / performance impacts of adding this information to base vault data returned
• influence vaults have specific not on chain fees (or breakdowns) that don't reflect always on strategies - ensure we have a robust way to handle multiple influence strategy fee set ups for any future considerations

Example

A target replacement for this look up information would be code like this
