Subject: Add deprecated feature and migrate string_proc to just_fmt

- Add `deprecated` feature flag to Cargo.toml
- Gate `string_proc` module behind both `deprecated` and `string_proc`
  features
- Replace internal `string_proc` dependency with `just_fmt` crate in
  constants macros
- Mark all `string_proc` modules as deprecated with migration
  instructions
- Remove `string_proc` dependency from sheet system
