- Move privacy toggle button from dashboard-only to global breadcrumbs bar
(desktop) and mobile top nav so it's accessible on every page
- Add _privacy_mode_check.html.erb inline script in <head> to prevent
flash of unblurred content on first page load (same pattern as dark mode)
- Improve Stimulus controller: add iconOn/iconOff targets to toggle between
eye/eye-off icons; update aria-pressed on all toggle targets simultaneously
- Remove hover-unblur (blur(4px) on hover) from CSS for security; add
pointer-events: none to prevent interaction with blurred values
- Move i18n key from pages.dashboard scope to layouts.application scope;
add privacy_mode translation to all 12 locales (EN, DE, FR, ES, CA,
NL, NB, PT-BR, RO, TR, ZH-CN, ZH-TW)
- Stimulus controller on global layout (persists across all pages)
- CSS blur effect on .privacy-sensitive elements (8px active, 4px on hover)
- localStorage persistence survives page navigations
- Toggle button on dashboard with aria-pressed for accessibility
- Applied to 28+ views: accounts, budgets, transactions, reports, etc.
Fixes: UTF-8 encoding, global controller mount, aria-pressed attribute
