* chore(ui): upgrade the dashboard to React 19
Bumps react and react-dom from 18.3.1 to 19.2.8 with matching @types. Next 16 already required a React 19 peer, so this aligns the dashboard with what the framework expects and unblocks Base UI and shadcn work that assumes the React 19 ref model.
React 19 passes ref through as a regular prop, so the setup file's forwardRef tripwire and the ref-forwarding test's forwardRef case no longer describe real behavior; both now assert the React 19 contract instead. useRef<T>(null) now yields RefObject<T | null>, which is the one prop type MessageList had to widen.
* test(ui): wait for a Base UI select popup to open before clicking an option
The option lands in the DOM one render before the popup finishes entering, while its positioner still carries pointer-events: none, so clicking it throws. Waiting on the option's text alone was a race that React 19's flush timing loses, which is why four ToolPolicies cases went red on the bump.
chooseSelectOption in test-utils opens the trigger, finds the option by role, waits for it to stop being pointer-blocked, then clicks. It also replaces the last-match-by-text hack, which only worked because the popup happens to portal after the table.
* refactor(ui): replace hand-rolled query-param routing with nuqs
The dashboard carried five copies of the same pushState-based detail
routing hook plus a shared navigateWithParams helper, each with its own
plumbing test and a copy-pasted reactive useSearchParams mock in
component tests. nuqs provides the same shallow history-API routing
behind useQueryState/useQueryStates, so the key, team and org hooks are
deleted in favor of inline useQueryState at their single consumers,
while the models and logs hooks keep their interfaces but drop their
hand-rolled internals. Component tests now mount NuqsTestingAdapter
(via renderWithProviders or locally) instead of patching window.history,
and URL assertions go through onUrlUpdate spies that can additionally
distinguish push from replace, which the old window.location checks
could not
* test(ui): assert browser back closes the log drawer after in-drawer selection
Greptile flagged that the nuqs port of the switching-logs test stopped
at asserting emitted push and replace modes. The test now replays those
recorded modes against a history stack and performs the back step, so a
regression to push-on-select or broken URL-derived drawer state fails
the test instead of passing silently
The team settings guardrails dropdown always rendered the Global and
Other headers, so a proxy with no global guardrails showed an empty
Global heading above the list.
