fix return type and ensure proper handling of Wei in formatWei function

[viktorking7]

What changed? Why?

• Changed: The formatWei function was updated to properly handle bigint values for Wei.
• Reason: Previously, the function returned a number or a string ('...') when the wei parameter was undefined, but it didn’t properly handle the conversion from Wei to Ether and then back to Wei. The update ensures that the function returns the correct parsed Ether value after formatting Wei.

Notes to reviewers

• This change modifies the return type of the formatWei function. Please pay special attention to the handling of edge cases, especially when the wei parameter is undefined.
• Ensure the precision and rounding of the values are handled correctly when converting from Wei to Ether and back to Wei.

How has it been tested?

• Manually tested with various values for wei, including both defined and undefined cases.
• The function has been validated to ensure that for defined wei values, the output is a properly formatted number, and for undefined, it returns '...'.
