fix: Update schemas for contracts to prevent collisions

[0xFable]

Avoids this problem

warning: output filename collision. The bin target schema in package vault-manager v0.1.0 (vault-manager) has the same output filename as the bin target schema in package epoch-manager v0.1.0 (epoch-manager). Colliding filename is: The targets should have unique names. Consider changing their names to be unique or compiling them separately. This may become a hard error in the future; see https://github.com/rust-lang/cargo/issues/6313.
