Backend: add batch endpoints for target states, metrics, and device
health to replace O(N) individual API calls per poll cycle.
Frontend: use batch endpoints in dashboard/targets/profiles tabs,
fix Chart.js instance leaks, debounce server event reloads, add
i18n active-tab guards, clean up ResizeObserver on pattern editor
close, cache uptime timer DOM refs, increase KC auto-refresh to 2s.

When multiple rectangles overlap, the currently selected one is now
tested first for both click and hover, keeping its edges and body
interactive even when another rectangle sits on top.

Add core/modal.js with reusable Modal class that handles open/close,
body locking, backdrop close, dirty checking, error display, and a
static stack for ESC key management. Migrate all 13 modals across 8
feature files to use the base class, eliminating ~200 lines of
duplicated boilerplate. Replace manual ESC handler list in app.js
with Modal.closeTopmost(), fixing 3 modals that were previously
unreachable via ESC. Remove 5 unused initialValues variables from
state.js. Fix target editor to auto-select first device/source and
auto-generate name like the KC editor does.

Replace the single 7034-line app.js with 17 ES module files organized
into core/ (state, api, i18n, ui) and features/ (calibration, dashboard,
device-discovery, devices, displays, kc-targets, pattern-templates,
profiles, streams, tabs, targets, tutorials) with an app.js entry point
that registers ~90 onclick globals on window. No bundler needed — FastAPI
serves modules directly via <script type="module">.
