feat: Bedrock support — typed commands and ASCII labels

Geyser cannot deliver a chat clickEvent to Bedrock, and most emoji render
as tofu boxes there, so Bedrock players could see the reaction row but
neither read nor use it.

Messages carrying buttons are now built twice and sent per player rather
than via Bukkit.broadcast. Each reaction gains a per-platform label plus a
typed shortcut:

    uau: { java: "[😮]", texto: "[UAU]", comando: "wow" }

Typed fallbacks for every clickable interaction: /reagir, /legal, /wow,
/top, /f, /palpite and /votar, all acting on the most recent message so no
message id is needed.

Bedrock detection uses Floodgate's UUID scheme (high 64 bits zero) rather
than the Floodgate API, keeping it an optional runtime dependency.
/canalhandia plataformas lists who is online and on which platform.

Reaction config moves from a flat key->label map to a section per
reaction; the old flat form is still accepted and gets an ASCII fallback
derived from the key.
