New module cloud_sync/icons.py:
- CLOUD_SVG, STORAGE_SVG: card glyphs (Material Icons, Apache-2.0)
- WARNING_BADGE_SVG, PLUS_BADGE_SVG, SYNC_BADGE_SVG: header badges
(hand-rolled — circle + vector primitives, no glyph font dependency)
- svg_pixmap(svg, size): QSvgRenderer-backed rasteriser; dual-binding
helper falls back from PySide6 to PyQt6.QtSvg.
Wired into ui_qt.py:
- Conflict dialog: warning badge SVG (light disc + dark !), cloud
card SVG, storage card SVG. Drops the QSS circle hack — entire
badge is one pixmap now.
- Login dialog: plus badge SVG (Prism-green disc + dark +).
- Progress window: sync arrow badge SVG (Prism-green disc + circular
arrow + head).
QSS shed: no more bg/border-radius/font-size acrobatics for badges
since the SVG includes the disc. Card icons are crisp at any DPI.
52 tests still green; pyz grows ~5 KB for the SVG strings + the new
icons module.
