Follow-up to #20525, picks up the clipboard + mouse/pointer events asks
from the "Allow to copy to clipboard in front-component" Slack thread.
`navigator.geolocation` and `getBoundingClientRect` are intentionally
out of scope until we have a permission model.
### `copyToClipboard` host API
New SDK function `copyToClipboard` (in `twenty-sdk/front-component`)
that goes through the host bridge to `useCopyToClipboard` in
`twenty-front`:
```ts
import { copyToClipboard } from 'twenty-sdk/front-component';
await copyToClipboard('hello');
```
Host-side hardening (front-component code is untrusted):
- Drops anything that isn't a non-empty string
- Caps payload at 64KB
- Throttles to 1 call/sec per front-component instance
- Snackbar shows a truncated preview so the user can spot a mismatch
between the affordance they clicked and what actually got copied
### `mousemove` and pointer events
Added to `COMMON_HTML_EVENTS` (and the React mapping) so they fire on
every HTML tag the renderer ships: `mousemove`, `pointerdown/up/move`,
`pointerover/out/enter/leave/cancel`. Generator rerun for
`remote-elements.ts` and `remote-components.ts`.
`SerializedEventData` now also forwards pointer geometry: `pointerId`,
`pointerType`, `pressure`, `tangentialPressure`, `tiltX/Y`, `twist`,
`width/height`, `isPrimary`. Existing positional fields are unchanged.
### Coverage
- New Storybook stories: `HostApi/CopyToClipboard` and
`HtmlTag/Grouping/Div/Events::PointerMove`
- `useFrontComponentExecutionContext` unit tests cover the API call,
preview truncation, type guard, length cap, and rate limit
- Renderer Storybook suite 227 → 229, prebuild bundle count 219 → 221
