refactor(tests): overhaul visual tests — single server, mock emails, fix init_db

- Consolidate 3 duplicate server processes into 1 session-scoped
  live_server fixture in conftest.py (port 5111, shared across all
  visual test modules). Reduces startup overhead from ~3× to 1×.

- Fix init_db mock: patch padelnomics.app.init_db (where it's used)
  instead of core.init_db (where it's defined). The before_serving
  hook imported init_db locally — patching core alone didn't prevent
  the real init_db from replacing the in-memory test DB.

- Keep patches active through app.run_task() so before_serving hooks
  can't replace the test DB during the server's lifetime.

- Force RESEND_API_KEY="" in the visual test server subprocess to
  prevent real email sends (dev mode: prints to stdout, returns "dev").

- Remove 4 screenshot-only no-op tests, replace with single
  test_capture_screenshots that grabs all pages in one pass.

- Fix test_planner_tab_switching: remove nonexistent "metrics" tab.

- Delete ~200 lines of duplicated boilerplate from 3 test files.
