Add TerapiaBinaural Radar 7D PRO plugin summary document

[gennarovela]

Motivation

• Add a concise product summary documenting the TerapiaBinaural® – Radar 7D PRO WordPress plugin features, access model, data storage and UI integration for project documentation and onboarding.

Description

• Add docs/terapiabinaural-radar-7d-pro.md containing a high-level overview of the plugin, admin capabilities, style manager, CPT tb_atendimento and postmeta keys (_tbr_data, _tbr_report_text, _tbr_patient_password), and the UI's app.js/app.css AJAX integration.

Testing

• No automated tests were run because this is a documentation-only change.
