The "Total SDP balance" widget disagrees with other balance views and omits SOL

[resourcefulmind]

Area: Dashboard / balances

Three balance surfaces report different totals for the same wallets:

• Payments > Overview, "Total SDP balance": $20.00 (USDC only)
• Wallets detail page, "Total balance": $200.99 (SOL and USDC)
• Home, "Total Balance": $368.72 (all wallets, SOL and USDC)

The balance API returns a usdValue for SOL, so the data is available. The Payments Overview widget is the only surface that omits it. Showing $20 (or $0 before any stablecoin is added) while the wallets hold roughly $180 of SOL tells a user they have far less than they do.

Reproduce

curl "$BASE/v1/wallets?includeBalances=true" -H "Authorization: Bearer $KEY"
#   SOL rows include a usdValue

Impact: the headline balance on the payments screen is wrong and contradicts two other pages.
Suggested fix: include every asset the balance API values, SOL included, in the Payments Overview total, or label it explicitly as stablecoin-only. Reconcile the three surfaces so they agree.

Going to park this here for now. We're unsure how we want to price issuance and other assets yet, and what to display. Will reconcile internally on what to do with pricing.
