Fix UI review issues: accessibility, i18n, duplicate IDs, URL overflow

- Rename duplicate id="settings-error" to "device-settings-error"
- Add missing i18n key value_source.scene_sensitivity.hint (en/ru/zh)
- Add accessible label to password-toggle and Stop All buttons
- Add aria-hidden toggle on connection overlay
- Fix static image URL overflow with ellipsis truncation
