## PR description
- Adds `enqueueSnackbar` to the front component host communication API,
allowing front components to display snack bar notifications (success,
error, info, warning) to the user.
- Introduces `frontComponentId` to the `FrontComponentExecutionContext`
and a `useFrontComponentId` hook, enabling front components to identify
themselves (used for dedupe keys).
- Wires error/success notifications into the `Action`, `ActionLink`, and
`ActionOpenSidePanelPage` SDK components -> actions now catch errors and
display them as snack bars, and `Action` supports an optional
`notifyOnEnd` prop for success feedback.
