feat(ui): partial react rewrite (#77)

## Summary by Sourcery

Export backend data structures to TypeScript for the new React-based UI
and update CI to build additional targets.

New Features:
- Generate TypeScript definitions for core backend structs and enums
used by the UI.
- Now use our own Azure app(_DropOut_) to finish the authorize process.

Enhancements:
- Annotate existing Rust models with ts-rs metadata to control exported
TypeScript shapes, including tagged enums and opaque JSON fields.

Build:
- Add ts-rs as a dependency for generating TypeScript bindings from Rust
types.

CI:
- Extend the Semifold CI workflow to run on the dev branch and build
additional Linux musl and Windows GNU targets using cross where needed.
