Adds brightness (0.0-1.0) to KeyColorsSettings, applies scaling in the
KC processing pipeline after smoothing, exposes a slider on the WebUI
target card, and creates a HA number entity for KC target brightness.

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">.
