improve dashboard usability and fix backend TS build errors

Frontend: fix HeroUI Switch usage across the whole app (Content/Control/
Thumb composition was missing, so no toggle ever rendered visibly),
replace raw channel/role ID text fields with proper name-based dropdowns
(ChannelSelect/RoleSelect) backed by the existing /guild/resources
endpoint, redesign Automod's filters as inline toggle rows, turn the
Ticket Pipeline tab into a drag-and-drop Kanban board, narrow the
sidebar further and rework its collapse toggle and profile footer, and
add a Discord-style message preview for Welcome/Support Login.

Backend: fix the ~50 TypeScript build errors blocking `npm run build`
(SlashCommandBuilder typing, discord.js v14 channel-union guards,
Prisma JSON null handling, logger.warn signature, and related type
narrowing) so the project compiles cleanly again.
