fix(discord): use GuildInteractionUser.Permissions instead of REST guild lookup

Replace REST GetGuildAsync/GetGuildUserAsync calls with authoritative
member.Permissions from the slash-command interaction payload. Discord
already resolves channel/guild permissions in the interaction JSON, so
we no longer need to fetch the guild via REST (which returns 404 when
the bot is not a REST member of the guild, e.g. user-installed apps).

Keep a best-effort GetGuildAsync call only to obtain OwnerId for the
permission checker fallback, swallowing 404 silently.

Bump version → 3.0.7
