Fix/doc improvements

[TobiasAdler]

Description

• Replaced 'sensible data' with 'sensitive data' since the term 'sensible' fails to provide an accurate depiction of the nature of that data
• Set sensible data methods @Deprecated
• Updated 'sensible data' to 'sensitive data' in docs
• Removed unnecessary unique() call in 'Radio buttons' section of documentation since the value already makes it unique and the call would require the Locator to be casted to PreparedLocator
• Added 'Timings View' section to docs
• Updated LayoutCheck pixel comparison screenshot in docs
