- Created lib/core/semantics/ with semantic ID constants and helper widget
- Enabled SemanticsBinding on web builds for accessibility tree exposure
- Added semantic IDs to:
- ProfileDropdown (button, settings, theme options, logout)
- TopHeaderBar room tabs (frontHall, controlRoom, security, parlor)
- NavPanel items (nav_item_{id})
This enables browser automation tools like Puppeteer and WebDriver to
discover and interact with Flutter widgets via the accessibility tree.
