- Delete Blade components, component classes, Livewire components and
views that nothing uses after the redesign.
- Delete tests that only compare Blade/CSS source text; keep the source
checks for authorization gates, stable wire:key values and escaping.
- Update stale tests to the current UI and behaviour.
- Update DESIGN.md to the current navigation and layout.
- Add a lesson: test behaviour, not source markup.

Add responsive overflow handling and dedicated action menus for application,
service, database, and server headings, while improving upgrade and email
settings flows and returning 404s for missing deployment environments.
Refactor upgrade state initialization into a shared `refreshUpgradeState()`
method used by both `mount()` and `checkUpdate()`. The method now uses
`version_compare` to validate upgrade availability and clears the
`new_version_available` flag in InstanceSettings when the current version
is already equal to or newer than the latest version, preventing stale
upgrade notifications from persisting after a successful update.
Covers Upgrade Livewire component mount behavior for:
- initializing latest version from cached versions data
- falling back to 0.0.0 when versions cache is unavailable
