feat: implement mute conversation support for Mastodon

This feature allows users to visually hide muted conversations from the Home timeline. It includes:

- Automatic filtering of muted posts in Home.

- Immediate visual removal of posts when muting a conversation.

- New 'mute_conversation' action in context menu and keyboard shortcuts.

- Default shortcut: Alt+Win+Shift+Delete

- Win10/11 shortcut: Ctrl+Alt+Win+Backspace
