fix: skip cached state override when bot ignores command (#213)

[bluetoothbot]

What

When Switchbot.turn_on/turn_off get a "command ignored" reply (0x03 0xff 0x00, typically on back-to-back presses), don't flip the cached isOn state. Only override the state when _check_command_result returns True.

Why

Closes the latent half of #213. The bot's own protocol distinguishes acceptance (0x01 0x48 0x90) from rejection (0x03 0xff 0x00) and _check_command_result(result, 0, {1, 5}) already returns False for the rejection case — but the next line ran self._override_state({"isOn": True}) unconditionally, so HA's cached state flipped to on even when the device never actuated.

That makes the back-to-back press behaviour observable in the issue: log shows Turn on result: 03ff00 -> {'isOn': True} for the second press, and HA happily reports the bot as on despite no physical actuation. The 8.5s disconnect timer + a brief delay between commands is still the user-side workaround; this PR just stops the library from lying about state when the command is rejected.

How

Two-line gate in bot.py:

ret = self._check_command_result(result, 0, {1, 5})
if ret:
    self._override_state({"isOn": True})  # or False, for turn_off

Behaviour for the success path (notification byte 0x01 or 0x05) is unchanged.

Testing

• New tests/test_bot.py covers turn_on/turn_off for both accepted and rejected results, plus an inverse-mode regression. (No existing test file for the Switchbot bot device class.)
• Full suite: 1218 passed.
