Initial commit: Phoenix LiveView demo for interactive data tables with filtering, sorting, pagination, URL state, and progressive enhancement

Implements a fully-featured action requests table in a single LiveView module using Flop, Ecto, and SQLite. Includes:

- Fuzzy search, status/assignment filters, column sorting, 25-per-page pagination
- Real-time updates, bookmarkable URLs via `handle_params/3`
- JS-disabled fallback with GET forms (no duplicate logic)
- 1,000,000 seeded records, Tailwind + DaisyUI styling, light/dark themes
- Comprehensive README with comparisons to Django+React/Rails+React stacks
- 31 tests covering all scenarios

Tech: Phoenix 1.8+, LiveView, Flop, Ecto, SQLite, Elixir 1.15+
