Extends weather's experimental Chromium+Jinja2 render style to battery, text, tasks, static image, whiteboard, and calendar (all four view modes -- agenda/today_tomorrow/week/month), and gives the photos widget its own genuinely independent palette + dithering strength. Photos: Frame.photo_palette_rgb/photo_dither_strength (mirroring the existing palette_rgb/dither_strength), with a second "Photos configuration" card in Advanced Configuration. widgets/photos.py's render() quantizes itself against these before returning -- no render_panel changes needed, since photos is the only widget that genuinely needs a different reference palette and can carry that itself, the same way modern-style widgets already self-dither via ordered_dither. Battery/text/tasks/static image/whiteboard: same render_style pattern weather established (render_style column, html_render.py build function, Jinja2 template, dialog toggle). Static image/whiteboard get their first-ever visual chrome (a rounded-corner shadowed card, shared framed_image.html.jinja) since classic draws them with zero frame at all. Fixed the same "preview endpoint bypasses render_style" bug weather originally shipped with, for tasks/static/whiteboard/ calendar's preview endpoints. Calendar: own module (app/calendar_html_render.py, mirroring calendar_render.py's separation from the simpler widgets) covering all four view modes, not just agenda -- reuses calendar_render's own private helpers so event colors/times/weather/month-grid math match classic exactly. Found and fixed two real cross-day layout bugs along the way: a per-day header height that varied based on whether that specific day had a weather entry (misaligning where every other day's event rows started across the week/month grid), and regular-weight small text being fragile under Bayer ordered dithering (out-of-month day numbers degraded into unrecognizable speckle) -- fixed by using bold everywhere and de-emphasizing via size instead of weight/gray, since gray text has the same dithering fragility this project's PIL renderers already avoid for exactly this reason. Migrations 32-38 (Frame's two new columns, then one render_style column per widget config table). 452 tests passing, including new dispatch/ migration coverage per widget type and a dedicated photos test proving photo_palette_rgb produces genuinely independent quantization from the frame's main palette_rgb.
