This commit modifies the UI to improve the message list's readability.

When multiple messages are sent consecutively by the same user, the user's name and avatar are now only displayed on the most recent message in the sequence. This change creates a more condensed and cleaner visual appearance for message bubbles from the same sender.

This commit introduces several UI enhancements to the messaging feature:

- Adds a `MessageActionsBottomSheet` that appears on a long press of a message item, providing options to Reply, React, and Copy.
- Implements `getMessageBubbleShape` to create chat bubble-style shapes for messages, connecting them visually if they are from the same sender consecutively.
- Refactors `MessageItem` to use the new bubble shapes and integrate the bottom sheet on long-click.
- Adds `MessageStatusIcon` to visually represent the delivery status of outgoing messages.
- Moves reaction rows to be overlaid at the bottom of the message bubble for a cleaner look.

This commit introduces a quick emoji reaction feature to the messaging screen.

When a user long-presses a message, a bottom sheet now appears with a row of frequently used emojis for quick reactions. It also includes an option to open a full emoji picker for more choices.

The list of frequent emojis is sourced from user preferences (`CustomEmojiPrefs`) and defaults to a standard set if no preferences are found. The UI has been updated to accommodate this new emoji row within the message actions bottom sheet.
