Fix front component pointer/mouse event coordinates (#21117)

Fixes https://github.com/twentyhq/twenty/issues/21000

Front-component event handlers read standard event fields
(event.clientX, event.offsetX, …), but these were always undefined. On
the remote side, serialized event data was passed only as the
CustomEvent's detail — and CustomEvent ignores every constructor option
except detail, so the values lived at event.detail.clientX and never on
the event object itself.

- Added `applySerializedEventProperties`, to copy a curated allowlist of
event-level keys onto the event. Element/target state (value, checked,
files, scroll, media props) stays in
`applySerializedEventTargetProperties`, applied to this (the dispatch
element = event.target).
- Added x/y to `SerializedEventData` and to host-side serialization in
`createHtmlHostWrapper`.
- Added an `svg-pointer `story + `createHtmlTagPointerStory`

Note: Also pinned @types/react to v18 so the renderer stops dragging in
React 19 types and breaking typecheck.
