fix(csr,ui): deliver component outputs to parent bindings

An output only reaches a parent @binding when the component calls
output.<name>(). Two separate faults meant most of the library never got
there, and both failed silently at each end.

HTML lowercases attribute names, so a parent's @sizeChange registered under
"sizechange" while the component emitted "sizeChange". The lookup missed, fell
through to a DOM dispatch, and the binding was never invoked. That made all 17
camelCase outputs undeliverable -- DataTable.pageChange and .rowClick,
Map.markerClick, ChatBubble.messageClick, LayoutSplitter.sizeChange and the
rest. invokeComponentOutput now falls back to a case-insensitive lookup, and a
csr test fails without it.

Separately, 18 components dispatched hand-built CustomEvents rather than
calling output.*. A bubbling event on the component's own root never reaches a
binding, because parent handlers live in a registry only the output proxy
reads. Card, Footer, Breadcrumb, Accordion, alert, Badge, AnnouncementBar,
AvatarGroup, ToggleCount and InputNumber now emit properly; Marquee, Map,
Timeline, List and SearchBox additionally declare the outputs they were
already firing. Dispatches on window are left alone -- that is how Toaster,
Modal and DataTable signal across component boundaries.

Verified in a browser both ways before and after: an AnnouncementBar
dispatching its own bubbling "dismiss" never reached a page-level @dismiss,
and reached it immediately once it called output.dismiss().

This corrects the audit, which called the LayoutSplitter failure "narrow and
unexplained" and read 32 dead outputs as 16 components needing a rebuild.
"Outputs work elsewhere" was an assumption; the components that worked
happened to use lowercase names and output.*. The dead-output ratchet drops
from 32 to 22, and a new test forbids the raw-CustomEvent pattern outright.
