[TASK] Standardize No Data Value vs Zero Value Display

[monaiuu]

Description

We need to establish a standardized way to clearly make distinction between no data values and actual zero values across our UI.

No Data (—)

• When the value is null/undefined
• When the data hasn't loaded yet
• When the value is not applicable for this context
• When there's an error fetching the data

Zero (0)

• When we have successfully fetched the data and it's explicitly zero
• When a calculation results in zero

Current Issues

In the Restake Vaults table we have inconsistent usage:

1. "Available" column: Uses mix of '0' and '—' for empty values; should be '0'
2. "Deposits" column: Uses '—' for empty values, should be '0'
3. "TVL | Capacity" column: Uses '—' for empty values, should be '0'

In the account component;

1. Rewards and Points: Uses '—' for empty values, should be '0'
