fix(ui): consolidate Orbit / Server / Live header dropdowns (#725)

* fix(ui): consolidate Orbit / Server / Live header dropdowns

The three header dropdown popovers each had their own container style.
Live used a glass utility class with backdrop-filter that read poorly on
many themes (reported by cucadmuh). Move all three onto the shared
`.nav-library-dropdown-panel` container — same bg, border, shadow and
radius via existing semantic tokens (`--bg-card`, `--border-dropdown`,
`--shadow-dropdown`, `--radius-md`). Item styles per dropdown stay
case-specific.

- NowPlayingDropdown: replace `glass animate-fade-in` with
  `nav-library-dropdown-panel animate-fade-in`; drop now-redundant inline
  borderRadius / boxShadow / zIndex; keep padding + gap for the
  user-list breathing room.
- OrbitStartTrigger: add `nav-library-dropdown-panel` alongside
  `orbit-launch-pop`. The component-local class is now reduced to the
  menu-specific min-width + tighter item gap; bg / border / shadow /
  radius / padding inherit from the shared container.
- Drop the unused `.glass` utility class; no other call sites.

 * The global **`selectstart`** handler assumed `event.target` was always an **`Element`**. Starting selection inside text (e.g. Now Playing **`[data-selectable]`** copy) could pass a **Text** node and crash with **`target.closest is not a function`**. The handler now resolves Text nodes to their parent element before applying allow/deny rules.
