The labelled icon-badge tiles were inconsistent: some used a same-hue
light tile + colored glyph (e.g. the Settings 2FA row: success.light tile
+ success.main glyph — low contrast, the reported "badly visible" icon),
and the solid-tile ones used the bright .main fill in dark mode without
darkening, so a white glyph on bright green/amber was low-contrast too
(DashProfile's success badge was ~1.9:1).
Add a single `iconBadgeSx(color)` helper (theme.ts): solid `<color>.main`
fill + white glyph, darkened in dark mode (FILLED_DARK_BG) so white stays
legible; `default` = neutral grey. Applied to every badge so they can't
drift: StatCard, DashActivityFeed, DashProfile (2FA badge), Dashboard
(2FA banner icon), AttendanceHistory (month tile), and the Settings 2FA
row tile (now solid green when required / grey when optional + white lock,
instead of the low-contrast light-green tile). Also switched DashProfile's
backup-codes warning callout from warning.light to a subtle warning wash
so its amber text stays readable in dark mode.
tsc -b --noEmit, npm run build, vitest 152/152 all clean.
