feat: admit an allowlisted operator's mention anywhere in an allowlisted guild

[EthanThatOneKid]

The internal tier requires the channel to be on DISCORD_INTERNAL_CHANNEL_IDS, so a mention from an allowlisted operator in any other channel is dropped even when the bot can read it. DISCORD_INTERNAL_GUILD_WIDE=1 makes the channel allowlist optional inside an allowlisted guild, keeping the guild allowlist and the user/role allowlist mandatory — a public or shared server stays closed, and the public tier is untouched. Off by default, so existing deployments do not change behavior.

This pull request, titled "feat: admit an allowlisted operator's mention anywhere in an allowlisted guild", allows an allowlisted operator to mention the bot in any channel of an allowlisted Discord guild, rather than being restricted to specific allowlisted channels. This change is controlled by a new DISCORD_INTERNAL_GUILD_WIDE environment variable, which, when enabled, makes the channel allowlist optional within an allowlisted guild, while the guild and user/role allowlists remain mandatory. This ensures that public or shared servers are not inadvertently opened.
