Fix help command not working in DMs

The `help` application command now functions as expected in DMs.
This shows both member-level and admin-level commands.

- Fixed `shop open` appearing in the DM slash command list
- Fixed `support_guild` not being included in `example-bot.conf`
- The following wards now require the `Guild` context to be passed to them:
	- `low_management`
	- `high_management`
