Updates the Blebox integration documentation to include newly supported input sensor devices and minor formatting fixes.

Changes:

• Document inputSensorD (2 inputs) and inputSensorQ (4 inputs) as binary sensor entities, including supported features and a polling/webhook note.
• Remove an extraneous whitespace-only line in the webhook configuration section.
• Add a blank line in the Simon 55 GO section to improve markdown formatting consistency.
