fix(tests): fix all 10 e2e test failures

- test_planner_calculate_htmx: click capex tab to reveal #tab-content
  (it starts display:none and only shows after tab switch)
- test_planner_quote_sidebar_visible_wide: use browser.new_page() instead
  of page.context.new_page() (default contexts don't support new_page)
- test_login/signup/quote_step1_loads: add .first to avoid strict mode
  violation from the feedback popover form
- test_language_switcher_en_to_de: verify footer link href + navigate
  directly instead of click (avoids off-screen element timing issues)
- test_landing_nav_no_overlap: filter display:none elements (zero-width
  bounding rect) so mobile-only nav div doesn't skew overlap check
- test_quote_wizard_*: replace schema.sql (doesn't exist) with migrate()
  approach matching test_visual.py and test_e2e_flows.py; fix URL from
  /leads/quote to /en/leads/quote; use label click for display:none pill
  radios; add missing required fields for steps 6 (financing_status +
  decision_process) and 8 (services_needed); add contact_phone to step 9

All 1018 unit tests + 61 e2e tests now pass.
