(draft)fix: swift bindings ffi setup

[reez]

Description

A bunch of changes since #25 that were awesome but swift bindings needed to catch up to them.

#28 solved getting framework to build.

This PR hopefully solves making the framework usable in iOS app again and clean up any unnecessary lines of code.

Tested in iOS app project

Notes to the reviewers

Add --features uniffi to cargo build commands:
Enables the uniffi feature during compilation of each static library to ensure the necessary FFI shim functions defined via #[uniffi::export] are included, fixing linker errors.

Use --manifest-path in uniffi-bindgen:
Generates Swift bindings directly from the Rust crate's Cargo.toml and source code, instead of inspecting a pre-compiled library artifact.

Remove mv commands for headers:
Deletes outdated commands that failed because they tried to move header files based on the previous .udl setup, which are no longer needed as xcodebuild finds the headers correctly elsewhere.
