[style] migrate to @prettier/plugin-oxc for faster formatting

Replace @trivago/prettier-plugin-sort-imports with @prettier/plugin-oxc
and @ianvs/prettier-plugin-sort-imports for improved performance.

Changes:
- Add @prettier/plugin-oxc (Rust-based fast parser)
- Add @ianvs/prettier-plugin-sort-imports (import sorting compatible with oxc)
- Remove @trivago/prettier-plugin-sort-imports
- Update .prettierrc to use new plugins and compatible import order config
- Reformat all files with new plugin configuration
