fix: resolve withdrawal phantom icons by token address

[de-snake]

Summary

Resolve withdrawal phantom icons from the existing address-based source → destination titles instead of their shared on-chain symbol. For example, several unrelated phantom contracts report wdwstETH; they must not all use the same icon.

• Keep raw symbols and explicit icon overrides unchanged.
• Add verified liUSD-1w → iUSD and rsETH → WETH title mappings.
• Cover all nine mapped pairs plus symbol fallback and explicit string/composite overrides.

Compatibility and release

Companion assets: Gearbox-protocol/static#317 (publish first).

Targets SDK master with the historical client-v3/main revision 1ca53dab (UI-kit 3.13.1). Current client main has migrated to SDK next and is covered by a separate next-branch change. The legacy client must consume the released SDK to select address-specific pair URLs. The static cp0x fallback remains synchronized for clients still using the old SDK.

Validation

• Focused Vitest: 15 tests passed.
• Typecheck passed; commit-time Biome passed.
• Built SDK and actual UI-kit renderer checks select exact paired filenames for nine withdrawal tokens and two PT-DETH maturities.
• Broader live audit has incomplete-chain/RPC limitations; this is not a claim of complete deployed multichain coverage.

Next-branch companion: #503.
