This commit makes the following improvements to the comment submission UI:
- Wraps the UI in a `Box` to center the content.
- Pads `Row` components.
- Adds an `Icon` in the submit button.
- Makes `TextField` fill available width and height.
These changes affect `App.kt`.
- Adds a `Sentiment` enum with friendly names and leading icons for `HAPPY`, `NEUTRAL`, and `SAD`.
- Replaces the previous `Greeting` class with this new `Sentiment` based approach.
- Updates the main UI (`App`) to use `FilterChip` for sentiment selection.
- Adds a `TextField` for user comments and a "Submit" button.
