chore(sns_aggregator): rebaseline candid bindings to didc 0.5.4

[yhabib]

Motivation

The daily aggregator-update workflow has been failing since the didc 0.4.0 → 0.5.4 bump in #7812. The committed bindings were never regenerated under the new didc, so the codegen output drifted from the checked-in files and ic_sns_ledger.patch no longer applied cleanly.

Changes

• Regenerated all five ic_sns_*.rs candid bindings under didc 0.5.4.
• Re-derived ic_sns_ledger.patch against the new baseline (same 3 derive-stripping hunks, updated context).
• Updated the list_topics call in upstream.rs to pass &ListTopicsRequest to match the new by-reference canister-method signatures.
