## Problem
We now export components under a subpath in ui-patterns to avoid barrel
files as they slow down every tools (from IDE to linters, etc.) and may
also affect bundles our users have to download.
## Solution
- Remove the UI patterns index file
- Fix invalid impors
Add generic building blocks for blocking features on High Availability
projects:
- useHighAvailability hook: HA state only (isHighAvailability,
isPending)
- HighAvailabilityDisabledEmptyState (full-page empty state)
- HighAvailabilityDisabledSectionNotice (in-section admonition)
The components carry a generic default title/description; consuming
pages pass their own copy via props. HA state is read from the project's
high_availability flag (same source as the High Availability badge on
the project home page).

## Summary by CodeRabbit
* **New Features**
* Added clearer messaging for features that aren’t available in High
Availability projects.
* Introduced a standard High Availability status check to help the app
adapt what it shows.
* **Bug Fixes**
* Hid non-applicable schema options when High Availability is enabled,
reducing confusion in selection lists.
