Reaction roles & autoroles

Two features in one module:

• Autoroles — roles assigned automatically when a member joins.
• Reaction roles — a posted message members use to self-assign roles, via buttons or a select menu (Sylo uses interactions, not raw reactions).

Dashboard: /guilds/<id>/m/roles.

Needs

• Manage Roles, with Sylo’s role above every role it hands out.
• Server Members intent (INTENT_GUILD_MEMBERS) for autoroles.

Settings

• Autoroles — a role list; also editable from the Welcome page’s “Give roles to new members”.
• Reaction-role messages — each has a channel, an embed, a style (buttons or a select menu), whether it’s exclusive (one role at a time), and a list of role + label (+ emoji) pairs.

Notes

• Editing a reaction-role message re-posts or edits it in place.
• Managed roles (bot roles, Nitro booster, etc.) can’t be assigned and are dropped from the picker.
