Subject: [PATCH 4/6] feat: run playwright against production build in CI

- Updated playwright.config.ts to support dynamic dev/production modes via PLAYWRIGHT_MODE env var.
- Added test:e2e:ci script to package.json to automate build and production E2E testing.
- Configured vite.config.ts preview server with COOP/COEP headers to support SQLite WASM in production mode.
- Added a new smoke test (smoke.spec.ts) covering app boot, responsive navigation, and security headers.
- Robustified existing E2E tests for CI environments (better selectors, mobile menu handling, increased timeouts).
- Fixed a SQL syntax error in public/db/schema.sql that blocked database initialization in bundled builds.
- Fixed a Web Worker bundling issue in src/db/connection-pool.ts by inlining the URL for Vite's static analysis.
- Updated CI workflow to install all necessary browsers and execute production E2E tests.

Subject: [PATCH 6/6] chore: run playwright e2e against production build in ci

This change updates the CI workflow to execute Playwright tests against a
production bundle (via `vite preview`) rather than the development server.

Key changes:
- Configured `playwright.config.ts` to switch ports and commands based on
  `PLAYWRIGHT_MODE=production`.
- Added `test:e2e:ci` script to `package.json` that builds the app before testing.
- Updated `vite.config.ts` to provide mandatory COOP and COEP headers in
  `preview` mode, enabling SQLite WASM in the production artifact.
- Fixed a syntax error in `public/db/schema.sql` regarding UUID defaults
  and a missing `verification_status` column.
- Refactored Web Worker initialization in `connection-pool.ts` for correct
  Vite bundling.
- Added a production smoke test and refactored existing E2E tests with a
  shared `ensureNavVisible` utility to handle responsive layouts.
- Updated CI workflow to install all Playwright browsers.
