fix(discord): DISCORD_ALLOW_BOTS=mentions/all now works without DISCORD_ALLOWED_USERS

Fixes #4466.

Root cause: two sequential authorization gates both independently rejected
bot messages, making DISCORD_ALLOW_BOTS completely ineffective.

Gate 1 — `discord.py` `on_message`:
    _is_allowed_user ran BEFORE the bot filter, so bot senders were dropped
    before the DISCORD_ALLOW_BOTS policy was ever evaluated.

Gate 2 — `gateway/run.py` _is_user_authorized:
    The gateway-level allowlist check rejected bot IDs with 'Unauthorized
    user: <bot_id>' even if they passed Gate 1.

Fix:

  gateway/platforms/discord.py — reorder on_message so DISCORD_ALLOW_BOTS
  runs BEFORE _is_allowed_user. Bots permitted by the filter skip the
  user allowlist; non-bots are still checked.

  gateway/session.py — add is_bot: bool = False to SessionSource so the
  gateway layer can distinguish bot senders.

  gateway/platforms/base.py — expose is_bot parameter in build_source.

  gateway/platforms/discord.py _handle_message — set is_bot=True when
  building the SessionSource for bot authors.

  gateway/run.py _is_user_authorized — when source.is_bot is True AND
  DISCORD_ALLOW_BOTS is 'mentions' or 'all', return True early. Platform
  filter already validated the message at on_message; don't re-reject.

Behavior matrix:

  | Config                                     | Before  | After   |
  | DISCORD_ALLOW_BOTS=none (default)          | Blocked | Blocked |
  | DISCORD_ALLOW_BOTS=all                     | Blocked | Allowed |
  | DISCORD_ALLOW_BOTS=mentions + @mention     | Blocked | Allowed |
  | DISCORD_ALLOW_BOTS=mentions, no mention    | Blocked | Blocked |
  | Human in DISCORD_ALLOWED_USERS             | Allowed | Allowed |
  | Human NOT in DISCORD_ALLOWED_USERS         | Blocked | Blocked |
