Persist and restore selected project and environment across page reloads

- Add refreshOrganization/refreshProject/refreshEnvironment to context store — update value and localStorage without clearing child selections
- OrgSelector: use refreshOrganization when same org is already stored, preventing the chain that was clearing project and environment
- ProjectSelector: watch org ID (not object ref) so refresh doesn't retrigger; add autoSelectProject to restore stored project or auto-select single project
- EnvironmentTabBar: watch project ID; skip env-clear on initial mount; add autoSelectEnvironment to restore stored env or fall back to first
- Fix test fixtures missing isPrimary field; update EnvironmentTabBar tests to match v-select implementation; add tests for restore behavior
