clear the remaining type errors

- DiscordAccount seeded DiscordStatus without its two nullable fields.
- bug-report typed reporter.name as string, but users.name is nullable; and the
  Discord upload wrapped a Buffer directly in a Blob.
- Lucide icons take no `title` prop, so the sync spinner's tooltip moved to a
  wrapping span.
- DesktopView cast its dynamic import to a type that included `| null`.
- dock PUT cast the request body straight to string[]; it now rejects anything
  that is not an array of strings instead of writing it to the database.
- buildZodSchema assembles a mutable record, since z.ZodRawShape is readonly in
  zod v4.
- The dev-server proxy forwards Bun's `string | Buffer` frames through a helper
  that satisfies WebSocket.send without copying.

bunx tsgo is now clean.
