Introduce support for web chat integration.

- Replaced synchronous permission checks with asynchronous LuckPerms user loading.
- Added `getOrLoadUser` utility to simplify user-related operations.
- Introduced web-originated chat command processing via new `PunishmentCommandBuilder` and `PunishFromWebHandler`.
- Updated `MuteServer`, `ToggleGlobalChat`, and `ToggleableForCustomChannel` to use async permission checks.
- Added test suite for `PunishmentCommandBuilder`.
- Expanded chat handling to process party messages from web events.
