Replace the 847-line client-side planner with an HTMX architecture:
- All tab content (CAPEX, Operating, Cash Flow, Returns, Metrics) rendered
server-side as Jinja2 partials; slider changes POST to /planner/calculate
which returns HTML; HTMX swaps into #tab-content
- Merge _PLANNER_TRANSLATIONS into _TRANSLATIONS; delete get_planner_translations()
and window.__PADELNOMICS_LOCALE__; all strings now {{ t.key }} in templates
- New form_to_state() and augment_d() helpers in routes.py; calculate endpoint
returns HTML instead of JSON; OOB swaps update header tag + wizard preview
- Add 5 Jinja2 filters: fmt_currency, fmt_k, fmt_pct, fmt_x, fmt_n
- Rewrite planner.js to ~200 lines: chart init on htmx:afterSettle, slider sync,
toggle management, wizard nav, scenario save/load, reset to defaults
- Add 7 new template partials: tab_capex, tab_operating, tab_cashflow,
tab_returns, tab_metrics, calculate_response, court_summary, wizard_preview
- Update test_phase0 to match new HTML-returning /calculate endpoint
