feat(solana-wallet-snap): use the shared EstimatedChanges UI component

[Julink-eth]

Explanation

This PR replaces Solana’s local EstimatedChanges implementation with the shared component from @metamask/snap-networks-utils.

Behavior change
Before: Solana showed its local loading skeleton again during a background re-scan, even when estimated changes were already available.
After: Previously estimated changes stay visible during re-scans, and scan errors only show the not-available state when there are no rows to display.
Notes
Keeps Solana-specific formatting and localization in the wrapper.

Removes the now-unused Solana EstimatedChangesHeader, EstimatedChangesSkeleton, and AssetChange components.
Adds/updates tests and changelog entries.
