## What kind of change does this PR introduce?
Bug fix. Resolves
[FE-4192](https://linear.app/supabase/issue/FE-4192/org-and-project-selectors-sometimes-dont-register-selections).
## What is the current behavior?
Navigation actions sometimes nest links inside command or dropdown menu
items. Closing the menu during selection can prevent the nested link
navigation from registering.
## What is the new behavior?
- Adds a documented Studio CommandItemLink composition that wraps
command items with their navigation link.
- Migrates all Studio command-item links, including organisation,
project, function, database, branch, and integration actions.
- Uses the dropdown menu asChild composition for both
infrastructure-diagram Manage replica actions.
- Preserves native link behaviour and leaves disabled command items
non-navigable.
## To test
- [ ] [Organisation and project
selectors](https://studio-staging-git-dnywh-fe-4192-selector-links-supabase.vercel.app/dashboard/org):
open the organisation selector and try an organisation, All
Organizations, and New organization. Open a project, then use the
project selector to switch projects and open New project. Confirm every
action navigates on the first click.
- [ ] [Branch
selector](https://studio-staging-git-dnywh-fe-4192-selector-links-supabase.vercel.app/dashboard/project/_):
in a project with branching enabled, open the branch selector. Switch
branches and select Manage branches. Confirm both navigate on the first
click.
- [ ] [Database
selector](https://studio-staging-git-dnywh-fe-4192-selector-links-supabase.vercel.app/dashboard/project/_/observability/query-performance):
open the Source selector. Switch between the primary database and a read
replica if available, then select Create a new read replica. Confirm
selections apply and the footer action navigates on the first click.
- [ ] [Function
selector](https://studio-staging-git-dnywh-fe-4192-selector-links-supabase.vercel.app/dashboard/project/_/auth/hooks):
select Add a new hook, choose a hook, select Postgres, then open the
Postgres function selector and select New function. Confirm it navigates
on the first click.
- [ ] [Infrastructure
diagram](https://studio-staging-git-dnywh-fe-4192-selector-links-supabase.vercel.app/dashboard/project/_/settings/infrastructure):
for a project with a read replica, select Manage replica from both
diagram variants. Confirm the replica settings open on the first click.
- [ ] On any navigational row above, modifier-click and confirm native
link behaviour is preserved.
