fix(wallet): match iOS token order and card-stack spacing (#1222)

Sort balances descending by exact native value, tiebreaking on token name
instead of mint address, so equal-value tokens (e.g. LaunchIt / Teddies)
order the same as iOS Session.balances.

Add a top inset and extra bottom content padding to the wallet list and trim
the header spacer so the token-card stack fully collapses, with the spacing
above the stack and below the last recent row matching iOS.
