Pull request overview

Upgrades the workspace’s stellar-rpc-client dependency to 26.0.0-rc.2 to pick up dependency/security fixes, along with small refactors needed to align with updated dependency APIs.

Changes:

• Bump stellar-rpc-client from 26.0.0-rc.1 to 26.0.0-rc.2 and refresh Cargo.lock.
• Remove direct jsonrpsee-* deps/usages from soroban-cli and switch relevant types/imports (e.g., serde::Serialize, reqwest::header::HeaderMap).
• Clean up various formatting / minor refactors (match guards, trailing commas) and update deny.toml advisory ignores.
