Add React UI and backend enhancements for dataflow

Browse Source 
- Add full React + Vite UI (src/pages: Sources, Rules, Mappings, Records, Import)
- Sidebar layout with source selector persisted to localStorage
- Sources: unified field table with Dedup/In-view checkboxes, CSV suggest, generate dfv view
- Rules: extract/replace function types, regex flags, input field picklist, test results
- Mappings: unmapped values with sample records, inline key/value editor, edit existing mappings
- Records: expanded row shows per-rule extraction and mapping output breakdown
- Import: drag-drop CSV, transform/reprocess buttons, import history
- Backend: add flags/function_type to rules, get_unmapped_values with samples, generate_source_view, fields endpoint, reprocess endpoint
- database/functions.sql: apply_transformations supports replace mode and flags; generate_source_view builds typed dfv views
- Server bound to 0.0.0.0, SPA fallback for client-side routing

# React + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
## React Compiler
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
## Expanding the ESLint configuration
If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the [TS template](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-react-ts) for information on how to integrate TypeScript and [`typescript-eslint`](https://typescript-eslint.io) in your project.
