chore: silence false-positive dead_code warnings

[aguilar1x]

Summary

The vc-vault-factory crate emitted 16 never used warnings on the native build. All are false positives: the Soroban contract macros (#[contract], #[contractclient], #[contractimpl]) generate the entrypoints (deploy / deploy_sponsored / is_vault), so the native dead-code linter can't see that the helper / storage / event functions are reachable through them.

Every flagged item has a real call site, and the WASM build (the real target) reports 0 warnings.

Change

Add crate-level #![allow(dead_code)] to contracts/vc-vault-factory/src/lib.rs, matching the pattern already used in vc-vault's lib.rs.

Poem

🐰 Hop hop, a warning quashed with care,
The allow attribute hops through the air,
Dead code whispers now kept at bay,
The compiler grins and hops away!
Let's tunnel forward to brighter days! 🍕
