Split monolithic index.html and style.css for maintainability
- Extract 15 modals and 3 partials from index.html into Jinja2 templates
(templates/modals/*.html, templates/partials/*.html)
- Split style.css (3,712 lines) into 11 feature-scoped CSS files under
static/css/ (base, layout, components, cards, modal, calibration,
dashboard, streams, patterns, profiles, tutorials)
- Switch root route from FileResponse to Jinja2Templates
- Add jinja2 dependency
- Consolidate duplicate @keyframes spin definition
- Browser receives identical assembled HTML — zero JS changes
